A rectangle has an area of (x - 17x + 72) square units. Since the area of a rectangle is determined using the formula, A =

kw, what could be the length and width of the rectangle?

length = (x - 8) units and width = (x - 9) units

length = (x + 9) units and width = (x + 8) units

length = (x-6) units and width = (x - 12) units

length = (x + 12) units and width = (x + 6) units

Step-by-step explanation:

x² - 17x + 72 = 0

Sum = - 17

Product = 72

Factor = 8, 9

x² - 17x + 72 = 0

x² - 8x - 9x + (-8) * (-9) = 0

x (x - 8) - 9 (x - 8) = 0

(x - 8) (x - 9) = 0

Length = (x - 8) units

Width = (x - 9) units
