Question

The rectangle below has an area of x2 - 4x - 12 square meters and a length of x + 2 meters.

What expression represents the width of the rectangle?
X+2
Width
x² - 4x – 12
Width =
meters

Answer 1

w=(x-6)

Explanation:

x^2-4x-12=(x + 2)(w)

a=wl (area equals width times length)

x^2-4x-12=(x + 2)(w)

(x-6)(x+2)=(x + 2)(w)

(x-6)=w
