Question

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

Answer: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) unitsWidth = (x – 9) units
