Step-by-step explanation:

area of the rectangle = length * width

the statement tell us area of the rectangle = (f • g) (5)

(f • g) = (4x + 30) * (x - 1)

(f • g) (5) = (4 * (5) + 30) * (5 - 1)

(f • g) (5) = (20+30) * (4)

(f • g) (5) = 50*4

(f • g) (5) = 200

The function f (x) = 4x + 30 represents the length of a rectangle. The function g (x) = x - 1 represents the width of the rectangle. Use (f • g) (5) to determine the area of the rectangle.44650200
