Find and simplify an expression for the perimeter of the right triangle

Question

A right triangle has the hypotenuse of (9x+y-2), an adjacent side of (2x^2+5x-y), and an opposite side of (3y+x^2)

Answer 1

The perimeter of the right triangle or any triangle at the matter is the sum of its sides.

 

Perimeter = (9x + y - 2) + (2x² + 5x - y) + (3y + x²)

 

 

Combine like terms.

 

Perimeter = 3x² + 14x + 3y

 

Perimeter = x(3x + 14) + 3y
