Question

A rectangle has an area of (x2 − 17x + 72) square units. Since the area of a rectangle is determined using the formula, A = lw, 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:

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

    Step-by-step explanation:

    We need to factor

    x^2 – 17x + 72

    We need two numbers whose product is 72 and whose sum is -17.

    The numbers are -8 and -9.

    x^2 – 17x + 72 = (x – 8)(x – 9)

    Answer: length = (x − 8) units and width = (x − 9) units
