2(5x-7)=2x+10 what is the distributive property

X = 3

Step-by-step explanation:

first you would do 2 * 5x - 2 * 7 = 2x+10

second you'll get 10x- 14 = 2x + 10

third subtract the 2x by the 10x

fourth you'll get 8x

fifth then add the 14 to the 10

sixth 8x = 24

divide that by 8x to both sides

so then you get x=3

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
