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?

Since the perimeter of a triangle is merely the sum of all sides, the value of the perimeter would give us the length of the straw before it was folded. Given perimeter = 12x^2 - 6, where x = 1.5:

P = 12x^2 - 6
P = 12(1.5)^2 - 6
P = 21

Therefore, the length of the straw before it was folded is 21 inches.

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
