15 points and brainliest (show your work)! a square has a side length of 3x - 8 cm. if the perimeter of the square is 148cm, write an equation that can be solved to find the value of x. (hint: your equation will involve the distributive property.)

4(3x-8)=148

Step-by-step explanation:

Why this happens is that all sides of a square are always congruent so if 3x-8 is 1 side, then multiplying it by 4 is the same as the perimeter. If you want to find x, then distribute the 4 first. The result would be 12x-32=148. Then simply add 32 to both sides so the variable is on one side alone. Then divide 180 by 12 to get your x of 15. Hopefully this helps, Comment if you have any questions!:)
