If m ∠ ∠ ∠ ∠ 3 = 7x + 40 and m ∠ ∠ ∠ ∠ 4 = 2x + 23, find m ∠

M=3+7x+40=4+2x+23

M=3+7x+40-4-2x-23

M=5x+20

M=5x=20

M=5x:5=20:5

M=4

answer: .75 km

step-by-step explanation:

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
