The rectangle below has an area of x2144x 2 144 square meters and a length of x12x12 meters What expression represents the width of the rectangle class=

Respuesta :

Answer:

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
