F(x) = x2+9
g(x) = X-9
Find f(x)*g(x).

f(x)g(x) = x³ - 9x² + 9x - 81

General Formulas and Concepts:

Distributions - Expanding with FOIL (First, Outside, Inside, Last)

Step-by-step explanation:

Step 1: Define

f(x) = x² + 9

g(x) = x - 9

Find f(x) · g(x)

Step 2: Find

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%
