$P = 2 x^{2} + 12 x + 2$ $P = 2x^2 +12x+2$

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.

$P = - 5 x^{2} + 9 x + 7 x^{2} + 7 + 3 x - 5$ $P = -5x^2+9x +7x^2 +7 + 3x -5$

$P = 2 x^{2} + 12 x + 2$ $P = 2x^2 +12x+2$

What is the perimeter of a triangle with the following sides: (−5x2+9x),(7x2+7),(3x−5)(-5x^2+9x), (7x^2+7), (3x-5)?
