The area of a rectangle is x2 - 2x - 15 and the length of the rectangle is x + 3. Find the width of the rectangle.

Answers

Answer 1

Answer: Area of the rectangle= L* w
$x^(2) -2x-15$
On expanding;
$x^(2) -5x+3x-15$
=x(x-5)+3(x-5)
=(x+3)(x-5)
The width is (x-5)

Answer 2

Answer:

Answer:

Width of the rectangle is (x-5)

Step-by-step explanation:

We know that, the product of length and width gives the area of the rectangle.

The area of a rectangle is given as,

$\Rightarrow \text{Area of rectangle}=\text{Length}* \text{Width}$

$\Rightarrow \text{Width}=\frac{\text{Area of rectangle}}{\text{Length}}$

Factoring the area,

$=x^2-2x-15$

$=x^2-5x+3x-15$

$=x(x-5)+3(x-5)$

$=(x+3)(x-5)$

Putting it in the equation,

$\Rightarrow \text{Width}=((x+3)(x-5))/((x+3))=(x-5)$

Answers

h(x) = -5x - 10
h(-2) = -5(-2) - 10
h(-2) = 10 - 10
h(-2) = 0

The solution is 0.

The answer is D, zero. Here are the steps.

h(x) = -5x - 10

h(-2) = -5(-2) - 10

h(-2) = 10 - 10

h(-2) = 0

2. The. You subtract the amount of the video game from 388.25

You get 330.26

I hope this helps! Have a great day!

Vlad spent 20 minutes on his history homework and then completely solved x math problems that each took 2 minutes to complete. What is the equation that can be used to find the value of y, the total time that Vlad spent on his homework, and what are the constraints on the values of x and y?y=2x+20; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 20.
y=2x+20; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 20.
y=20x+2; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 20.
y=20x +2; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 20.

Marissa rode her bike to the park and back home. She lives 2 3/10 miles from the park. How many miles did Marissa ride her bike in all. Give u 20 points

Answers

$2(3)/(10) +2(3)/(10) =((2*10)+3)/(10)+((2*10)+3)/(10) =(20+3)/(10)+(20+3)/(10)\n\n=(23)/(10) +(23)/(10) =(23+23)/(10) =(46)/(10) =4(6)/(10) =\boxed{\bf{4(3)/(5)}}$

Marissa rode 4 3/5 miles in all.

Well since she rode 2 3/10 to the park and back the problem would be 2 3/10 +2 3/10 which would equal 4 6/10
hope that helps.

Which square root is between 4 and 5? Options: A) √10 B) √14 C) √24 D) √32
