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.
