Solve.The first side of a triangle is 10 feet longer than the second. The third side is 10 feet less than double the second. The perimeter of the triangle is 88 feet. Let s represent the length of the second side and write an equation. Do not solve the equation.
A. s + (s - 10) + 2(s - 10) = 88 B. s + (s - 10) + (2s - 10) = 88 C. s + (s + 10) + (10 - 2s) = 88 D. s + (s + 10) + (2s - 10) = 88
