Pablo folds a straw into a triangle with side lengths of 4x2 – 3 inches, 4x2 – 2 inches, and 4x2 – 1 inches. The perimeter of the triangle is 12x2 – 6 inches. If x = 1.5, what was the length of the straw before it was folded?

old question but will answer so this can be closed

the length is conserved when folding so you just need to plug x = 1.5 into the perimeter expression 12x^2 - 6
