In triangle xyz, a is the midpoint of xy, b is the midpoint of yz, and c is the midpoint of xz.
also, ay = 7, bz = 8, and xz = 18. what is the perimeter of triangle abc? explain.

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

5050

hope this !

a) 0,0; 1,1; and 2,2
