What is the missing length of a right triangle have 18 in and 30 in

b=24

Step-by-step explanation:

a²+b²=c²

18²=324

30²=900

900-324=576

√574=24

24²=576

576+324=900

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
