Question

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?

Answer 1

Let the sides be a, b, and c.

a = 3x - 4

b = x² - 1

c = 2x² - 15

x = 4

Substituting the value of x :

a = 3 × 4 - 4 = 8 feet

b = 4²-1 = 15 feet

c = 2 × 4² - 15 = 17 feet

Perimeter = a + b + c

= 17 + 15 + 8 = 40 feet

Answer 2

Answer:

40 feet
