An isosceles right triangle has a hypotenuse length that can be modeled with the function h(x) = x^2. The combined length of the legs can be modeled with the function L(x) = 2x.
Which function, p(x), can be used to find the perimeter of the triangle?
O p(x) = {V2 + x
O p(x) = x^2 + 2x
O p(x) = x2 + 4x
O p(x) = 2xV2 + 4x
