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? inches

The length of straw is 21 inches.

Step-by-step explanation:

Given :

Lengths of straw = , , inches.

Perimeter of the triangle is  inches.

Perimeter of triangle is sum of three sides .

Thus, when we open the triangle we obtain the length of straw thus perimeter is the length of the straw.

Given x = 1.5 inches

Put in perimeter, we get,

Length of straw = Perimeter of triangle= at x = 1.5 inches

Thus, the length of straw is 21 inches.
