Answer 3

To simplify the expression (5c + 8 + 9x) * 6 + 3 * (4c - 2 - x), you can use the distributive property to expand and combine like terms. Here's how you can do it step by step:

1. Distribute the 6 to the terms inside the first set of parentheses: 6 * 5c + 6 * 8 + 6 * 9x

This gives you: 30c + 48 + 54x

2. Distribute the 3 to the terms inside the second set of parentheses: 3 * 4c - 3 * 2 - 3 * x

This gives you: 12c - 6 - 3x

Now, the expression becomes: (30c + 48 + 54x) + (12c - 6 - 3x)

3. Combine like terms within each set of parentheses: 30c + 12c + 48 - 6 + 54x - 3x

4. Combine the like terms in the entire expression: (30c + 12c) + (48 - 6) + (54x - 3x)

5. Further simplify the expression: 42c + 42 + 51x

So, the simplified expression is: 42c + 42 + 51x
