Kat is painting the edge of a triangular stage prop with reflective orange paint. the lengths of the edges of the triangle are (3x – 4) feet, (x2 – 1) feet, and (2x2 – 15) feet. what is the perimeter of the triangle if x = 4?

40 feet.

Step-by-step explanation:

Given : The lengths of the edges of the triangle are feet, feet, and feet.

Since , the perimeter of any figure is the sum of all its edges.

Then the perimeter of the give triangle will be :-

At x= 4

Hence, the  perimeter of the triangle if x = 4 will be 40 feet.
