I know to find the perimeter you have to add all side lengths but how would you find the perimeter if this triangle?

    perimeter of the triangle is P = a+b+c where: a,b and c are the lengths of each side of the triangle

    Add the sides like you normally would. 5w + (-2w +15) + (w - 7)

    so let a = (w-7) b = (-2w+15) c = (5w) P = (w-7)+(-2w+15)+5w and combine like terms... wow mine is backwards. I wonder if order matters ?
