The side lengths of a triangle are given by the expressions 5x+3,5x+5,and3x-2.write and simplify a linear expression for the perimeter of the triangle.

Which ordered pair is a solution to the system of linear equations? 2x + 3y= 6 –3x + 5y = 10

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)
