You marked off your shop floor in a grid of 1 foot squares and Labeled them with Cartesian coordinates. To perform one task a worker must go from point (2,7) to point (10,6) then back to point (2,7). The worker walks in a straight line between points. How far does she have to walk?

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

i think it is c hope that

b. b < 1 might be the correct answer
