Answer:

D. [tex] x^2 + 3x - 88 [/tex]

Step-by-step explanation:

Area of rectangle = [tex] length (l) * width (w) [/tex]

Length of rectangle = (x - 8)

Width = (x + 11)

Area of rectangle = [tex] (x - 8)(x + 11) [/tex]

Expand the expression

[tex] x(x + 11) -8(x + 11) [/tex] (distributive property of multiplication)

[tex] x^2 + 11x - 8x - 88 [/tex]

Combine like terms

[tex] x^2 + 3x - 88 [/tex]

Expression for the area of the rectangle = [tex] x^2 + 3x - 88 [/tex]
