Matt built a cage for his snake. The top of the cage was in the shape of a right triangle. One leg of the top was 4x + 2 feet. The second leg of the top was 3x +1 feet. He built a second cage using the same format but he increased each side by 4 feet. Which expression represents the area, S, for the top of the second cage? 1. S = 6x2 + 5x + 1 2. S = 6x2 + 19x + 15 3. S = 6x2 + 20x + 1 4. S = 6x2 + 25x + 15
