what is the other binomial?

Answers

Answer:

11x² -3x

Step-by-step explanation:

We have the product of a sum, of two binomials and one of the initial binomials but we'd like to know the other one.

It's very much like A + B = C, and we have both B and C, but looking to find A.

What would you do in the ABC scenario?

You'd isolate A by transforming the equation to: A = C - B

In this case, C = 12x² - 5x and B = x² - 2x...

A = (12x² - 5x) - (x² - 2x) = 12x² - 5x - x² + 2x

A = 11x² -3x

The perimeter of a rectangular herb garden is 74 feet. If the length is 5 feet longer then 3 times it’s width what is the gardens width?

Answers

Answer:

width = 8 feet and length = 29 feet

Step-by-step explanation:

perimeter of a rectangle P = 2(L + W)

width W = x

length L = 3x + 5

P = 74 feet

74 = 2(3x + 5 + x)

37 = 3x + 5 + x

37 = 4x + 5

4x = 37 -5

4x = 32

x = 8

W = 8 feet

In triangle JKL, m of angle J = 90, m of angle K = 30, and m of angle L = 60. Which of the following statements about triangle JKL are true? Check all that apply.
A) KL= root 3 (JL)
B) KL= 2(JL)
C) JK= root 3 (JL)
D) JK= 2(JL)
E) JL= root 3/2 (KL)
F) JK= root 3/2 (KL)

Answers

Answer:

# Answer B is true ⇒ KL = 2(JL)

# Answer C is true ⇒ JK = √3(JL)

# Answer F is true ⇒ JK = √3/2(KL)

Step-by-step explanation:

* Lets explain the ratio between the sides of the triangle

- In Δ JKL

∵ The measure of angle J is 90°

∴ KL is the hypotenuse

∵ The measure of angle K is 30°

∴ JL is the opposite side to angle 30°

∵ The measure of angle L is 60°

∴ JK is the opposite side to the angle 60°

- There is a fact in the triangle which has angles 30° , 60° , 90°

# The length of the side opposite to the angle of measure 30° is

  half the length of the hypotenuse

∵ KL is the hypotenuse

∵ JL is the opposite side to the angle of measure 30°

∴ JL = 1/2 KL  OR KL = 2 JL

# The length of the side opposite to the angle of measure 60° is

  √3 the length of the opposite side to the angle 30°

∵ JK is the opposite side to the angle of measure 60°

∵ JL is the opposite side to the angle of measure 30°

JK = √3 JL

# The length of the side opposite to the angle of measure 60° is also

  half √3 the length of the hypotenuse

∵ JK is the opposite side to the angle of measure 60°

∵ KL is the hypotenuse

JK = √3/2 KL

- From the relation above

# Answer B is true ⇒ KL = 2(JL)

# Answer C is true ⇒ JK = √3(JL)

# Answer F is true ⇒ JK = √3/2(KL)

Each of 6 students reported the number of movies they saw in the past year. This is what they reported. 15,9,13,18,9,6, find the mean and median numbers of the movies that students saw.

Answers

Answer:

mean = 11.66666

median = 11

Step-by-step explanation:

To find the mean, add up all the numbers, then divide by how many numbers

mean = (15+9+13+18+9+6) / 6 = 70/6 = 11 .6666666

To find the median, put the numbers from smallest to largest. then take the middle number.  Since there is an even number, take the two middle numbers and average them

6,9,9,13,15,18

The two middle numbers are 9 and 13

(9+13)/2 = 22/2 = 11

a Potter uses 3/5 of a pound of clay to make a bowl how many bowls could the Potter make from 10 lb of clay​

Answers

Answer:

16

Step-by-step explanation:

Let's say x is the number of bowls.  If each bowl needs 3/5 pound of clay, then the total clay needed is 3/5 * x.  We know the total amount is 10 pounds.  Therefore:

10 = 3/5 x

Divide:

x = 10 / (3/5)

To divide by a fraction, we need to multiply by the reciprocal:

x = 10 * (5/3)

x = 50/3

x = 16 ⅔

We can't have part of a bowl, so we must round down.  The potter can make 16 bowls.

9 pounds of ground beef cost $40.32. What is the price per ounce?

Answers

The price per ounce of ground beef, when 9 pounds cost $40.32, is $0.28.

Calculating Price per Ounce of Ground Beef

To calculate the price per ounce for ground beef when given the price for 9 pounds, we will first need to know how many ounces are in 9 pounds. Since there are 16 ounces in 1 pound, 9 pounds is equivalent to 144 ounces (9 pounds × 16 ounces/pound).

Next, we divide the total cost of the 9 pounds of ground beef by the total number of ounces to find the price per ounce. The total cost given is $40.32.

Price per ounce = Total cost \/ Total number of ounces

Price per ounce = $40.32 \/ 144 ounces

Price per ounce = $0.28

Therefore, the price per ounce of ground beef is $0.28.

Barry is 8 years older than his sister. In 3 years, he will be twice as old as she will be then. How old is each now?

Answers

Final answer:

Barry is currently 13 years old and his sister is 5 years old. This is determined by setting up a system of equations based on the given information and solving for their current ages.

Explanation:

The question involves solving a system of equations to find the current ages of Barry and his sister. Let's let B represent Barry's current age and S represent his sister's current age. According to the problem, Barry is 8 years older than his sister (B = S + 8). In 3 years, Barry will be twice as old as his sister will be then (B + 3 = 2(S + 3)).

Write down the two equations: B = S + 8 and B + 3 = 2(S + 3).

Substitute B from the first equation into the second equation: (S + 8) + 3 = 2(S + 3).

Simplify and solve for S: S + 11 = 2S + 6.

Rearrange the equation to find S: S = 5.

Substitute the value of S back into the first equation to find B: B = 5 + 8, so B = 13.

Therefore, Barry is currently 13 years old and his sister is 5 years old.

The sum of two integers is -8.if one integer is 12 then the other is?

Answers

Answer:

2 and -10

Step-by-step explanation:

let the two integers be x and y.

so, x+y=-8---‐-------(1)

and,

x=y+12-------‐-----(2)

from (1) and (2),

(y+12)+y=-8

or, 2y=-8-12

or, y=-20/2

or, y=-10

substitutting the value of y in (2),

x=-10+12=2

therefore the required integers are 2 and -10.

Answer:

-20

Step-by-step explanation:

→ The sum of two integers is -8.

⇒ One will be called "x" and the other will be called "y"

→ One integer is 12 ( "y" )

Let's set up an equation x = ? and y = 12 so,

→ x + y = -8

( Substitute y for 12 )

→ x + 12 = -8

( -12 from both sides to isolate x )

→ x = -20

D) x2 - 8x - 24

Answers

Answer:

x^2-5x-24

Step-by-step explanation:

Final answer:

The product of the binomials (x + 3)(x - 8) is simplified using the FOIL method to get x² - 5x - 24. We multiply each term in the first parenthesis by each term in the second and combine like terms.

Explanation:

To multiply and simplify the expression (x + 3)(x - 8), we will use the FOIL method (First, Outer, Inner, Last). This method involves multiplying each term in the first parenthesis by each term in the second parenthesis.

First: x times x = x²

Outer: x times -8 = -8x

Inner: 3 times x = +3x

Last: 3 times -8 = -24

Next, combine like terms (-8x and +3x):

x² - 8x + 3x - 24 = x² - 5x - 24

The simplified form of the given expression is x² - 5x - 24, which corresponds to option C).

Driving across country, mike drove for 3 hours at a certain rate and for 4 hours at a rate 10 mph faster. If his total distance covered was 495 miles, then what was his slower rate?

Answers

Final answer:

Mike's slower rate of driving across country was 65 mph.

Explanation:

Let the slower rate be represented as r mph. The faster rate will be r+10 mph. The total distance covered (495 miles) is the product of the time and the rate:

The distance covered at the slower rate is 3r miles.The distance covered at the faster rate is 4(r+10) miles.

Adding up the distances, we get:

3r + 4(r+10) = 495

Simplifying the equation:

3r + 4r + 40 = 495

Combining like terms:

7r + 40 = 495

Subtracting 40 from both sides:

7r = 455

Dividing by 7:

r = 65

Therefore, the slower rate is 65 mph.

https://brainly.com/question/30164170

#SPJ11

The correct answer for the slower rate at which Mike drove is 65 mph.

To find the slower rate at which Mike drove, let's denote the slower rate as r mph. Mike drove at this rate for 3 hours. He then drove for 4 hours at a rate that is 10 mph faster than the slower rate, which would be r + 10 mph.

The total distance covered by Mike is the sum of the distances covered at each rate. We can set up an equation to represent this:

[tex]\[ 3r + 4(r + 10) = 495 \][/tex]

Expanding the equation, we get:

[tex]\[ 3r + 4r + 40 = 495 \][/tex]

Combining like terms, we have:

[tex]\[ 7r + 40 = 495 \][/tex]

Now, we need to solve for r We can do this by subtracting 40 from both sides of the equation:

[tex]\[ 7r = 495 - 40 \] \[ 7r = 455 \][/tex]

Dividing both sides by 7 to solve for r, we get:

[tex]\[ r = \frac{455}{7} \] \[ r = 65 \][/tex]

Therefore, the slower rate at which Mike drove is 65 mph.

What is the circumference of a circle with a diameter of 21 m? (use for pi)

Answers

Answer:

21π m, or ≈ 65.94 m

Step-by-step explanation:

Remember that π is the ratio between a circle's circumference and its diameter, or, in equation form:

[tex]\pi=\frac{c}{d}[/tex]

where c is the circumference and d is the diameter. If we want to find the circumference, we can just multiply that equation by d on both sides to get

[tex]c=\pi d[/tex]

Here, our d = 21 m, so our circumference would be

[tex]c=21\pi[/tex] m, or approximately 21(3.14) = 65.94 m

D=21m
R=21/2=10.5m
C=2*pi*r

65.94

So circumference of a circle with a diameter of 21m is 65.94m

ANSWER

A. 10,000

EXPLANATION

The given rational function is

[tex]f(x) = \frac{1}{x - 2} [/tex]

This function is not defined at x=2.

But as we are picking x-values that are closer and closer to 2, the functional values grows bigger and bigger positively or negatively without bounds.

Therefore a possible value of f(x) as x is close to 2 is 10,000.

The correct answer is A.
