Pablo folds a straw

vigil:

what do you think

vigil:

It's asking for the length of the straw prior to folding, which is equivalent to the perimeter of the triangle, given as 12x^2 - 6. It's also given that x=1.5. Simply substitute 1.5 as x. That would be 12(1.5)^2 - 6, then you'll get you final answer. Be sure to include units (in this case inches). The other values and sidelengths were just given to fool you, as the perimeter of the triangle is already given.
