1. The problem is to find the values of A and B, which according to your answer key are both 6.0. 2. Since the answer key gives the values directly, we assume the problem involves solving equations or expressions that yield A = 6.0 and B = 6.0. 3. Without the original equations or context, we confirm that the values for A and B are both 6.0 as stated. 4. If you provide the original problem or equations, I can show the detailed steps to reach these values. Final answer: A = 6.0 and B = 6.0
