Answer:

Step-by-step explanation:

The width of the rectangle is (x - 9)

(x + 4)(x - 9)

x^2 - 9x + 4x - 36

x^2 - 5x - 36

Answer:

W = ( x - 9 )

Step-by-step explanation:

The area of a rectangle is equal to the length times the width of the rectangle.

So we can say A = LW

A = (x^2 - 5x - 36)

L = (x + 4)

A = LW

W = A / L

W = (x^2 - 5x - 36) / (x + 4)

W = (x + 4) (x - 9) / (x + 4)

W = (x - 9)

Cheers.

What is the y-intercept of the graph of the function f(x) = x^2 + 3x + 5?
Semenov [28]

Answer:

(0,5)

Step-by-step explanation:

To find the y-intercept, substitute in 0 for x and solve for y.

y=x^2 + 3x + 5

y=(0)^2 + 3(0) +5

y=0+0+5

y=5

Since there is no x coordinate for a y-intercept, the answer is (0,5)

Triangle- interior angle<br> Please help !
sp2606 [1]

Answer:

x = 25

<B = 120 degrees

<C = 30 degrees

Step-by-step explanation:

Total angle measure of a triangle - 180 degrees

Add all the angles together to find the value of x

30 + 4x + 20 + x + 5 = 180

55 + 5x = 180

55 - 55 + 5x = 180 - 55

5x = 125

\frac{5x}{5} = \frac{125}{5}

x = 25

<B = 4(25) + 20

<B = 100 + 20

<B = 120

<C = 25 + 5

<C = 30
