Answer 3

It seems like you've provided two expressions and indicated that you want to evaluate them for specific values of variables. Let's solve each expression step by step:

Expression 1: 6 * 7 - 3 * 7a when a = 42 Expression 2: (a + 7) * b when a = -10 and b = 6

Expression 1:

Given expression: 6 * 7 - 3 * 7a Substitute a with 42: 6 * 7 - 3 * 7 * 42 Calculate: 42 - 882 Result: -840

Expression 2:

Given expression: (a + 7) * b Substitute a with -10 and b with 6: (-10 + 7) * 6 Calculate: -3 * 6 Result: -18

So, the results are:

• Expression 1 (a = 42): -840
• Expression 2 (a = -10, b = 6): -18
