Write an equation to represent the situation. Then, solve the equation.The triangle in the illustration is such that side a is twice as long as side b, and side c is 2 inches shorter than side a. The perimeter of the triangle is 33 inches. Determine the lengths of sides a, b, and c.
A. 2a + a + (2a - 2) = 33; a = 7 inches, b = 14 inches, c = 5 inches B. 2b + b + (2b - 2) = 33; a = 7 inches, b = 14 inches, c = 5 inches C. 2b + b + (2b - 2) = 33; a = 14 inches, b = 7 inches, c = 12 inches D. 2a + a + (2a - 2) = 33; a = 14 inches, b = 7 inches, c = 12 inches
