5(3x - 4) = -29 + 8x
solve for best gets brainliest!

-5(3x-4)=-29+8x
open the bracket on LHS
-15x+20=-29+8x
20+29=8x+15x
49=23x
x=49/23

We are solving for x. That means to put x on one side of the equation (usually on the left side) and everything opposite to x.

-5(3x - 4) = -29 + 8x ; Start
-15x + 20 = 29 + 8x  ; Distribute -5 across 3x and -4
-15x = 9 + 8x             ; Subtract 20 from each side of the equation
0 = 9 + 23x                 ; Add 15x to each side of the equation
-9 = 23x                      ; Subtract 9 from each of the equation
23x = -9                      ; The Reflexive Property of Equality
x = -9/23                      ; Divide both sides by the coefficient of x. Which is 23.

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
