Question

What is the perimeter of a triangle with the following sides: `(-5x^2+9x), (7x^2+7), (3x-5)`?

Answer 1

`P = 2x^2 +12x+2`

Explanation:

Perimeter is the sum of the sides of the triangle.

We will not get an actual numerical answer, but we will have an expression for the perimeter.

`P = -5x^2+9x +7x^2 +7 + 3x -5`

`P = 2x^2 +12x+2`
