The rectangle below has an area of x^2-144x
2
−144 square meters and a length of x+12x+12 meters.
what expression represents the width of the rectangle?

width = x - 12

Step-by-step explanation:

Area = x² - 144 ← difference of squares

x² - 144 = (x + 12)(x - 12) ← in factored form

Area = length × width

length = x + 12 ⇒ width = x - 12

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )
