3 0

Step-by-step explanation:

An x-intercept of a function occurs when f(x) = 0.

In f(x) = (x-8)(x+9), f(x) will be 0 if either (x-8) is 0 or (x+9) is 0.

Hence, f(x) = 0 when x = 8 or x = -9.

Answer:

x^2 +8x +12

Step-by-step explanation:

The area is the product of length and width. The product can be simplified using the distributive property.

A = LW

A = (x +6)(x +2) = x(x +2) +6(x +2)

A = x^2 +2x +6x +12

A = x^2 +8x +12
