The rate at which motor oil is leaking from an automobile is modeled by the function L defined by L(t) = 1 + sin(12) for time + 2 0. L(t) is measured in liters per hour, and t is measured in hours. How
much oil leaks out of the automobile during the first half hour?
(A) 1.998 liters
(B) 1.247 liters
(C) 0.969 liters
(D) 0.541 liters
(E) 0.531 liters

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
