Kiana walks from her house to Jo's house. She first walks west then walks south. How many blocks west does Kiana walk? How many south?

She goes from 4 to -4 west which is 8 blocks west

Then she goes south from +2 to -2 on the y axis which is 4 blocks south

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

the square root of what number? if you add that, then someone will probably answer the question.
