Question

An equilateral triangle has a side length of 3x^2 - 4x + 9. What is the perimeter of the triangle?

Answer 1

P = 9x^2 - 12x + 27

Explanation:

The perimeter of an equilateral triangle is 3 times the length of one side. Thus, the perimeter of the triangle whose side length is 3x^2 - 4x + 9 is

P = 3(3x^2 - 4x + 9), or:

P = 9x^2 - 12x + 27
