The side lengths of two triangles are shown. Represent the perimeter of each triangle with an expression in simplest form. Which triangle has a greater perimeter if x = 3? Will this be true for any positive value of x? Justify your response.
Replace x with 3 in each, and then add all the sides up. Im not sure about the second question, "Will this be true for any positive value of x? Justify your response".
Im hoping that someone else could answer that for you
