- Macy has a circular pool with a diameter of 18 feet. If she swims
around the pool 4 times, find the distance she will travel.

Calculating water volume of a pool requires a number of preliminary the measurements together to determine the complete perimeter, though what is really necessary is to measure only one side of square pool, then multiply by 4. So, a round pool with a 20-foot diameter has a circumference of 3.14 x

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

2x^2+5x+17
