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) units

    Width = (x – 9) units
