A submarine can descend at a speed of –2.5 meters / second. Suppose the submarine starts at a depth of –25 meters. How long would it take for the submarine to reach its maximum depth of –200 meters?

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
