The perimeter of a triangle is 32 feet. one side of the triangle is 11 feet longer than the second side. the third side is 9 feet longer than the second side. find the length of each side

Step-by-step explanation:

x+x+11+x+9=32

3x+20=32

-20 from each side

3x=12

divide by 3

x=4.

11+4=15

9+4=13

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
