Answer 3

To simplify the expression 10(3a-b)-17(b+2a), we can apply the distributive property and combine like terms.

Let's break it down step by step:

1. Distribute the 10 to both terms inside the parentheses: - 10 * 3a = 30a - 10 * -b = -10b

2. Distribute the -17 to both terms inside the parentheses: - -17 * b = -17b - -17 * 2a = -34a

Now, let's combine the like terms:

- 30a - 10b - 17b - 34a

Combine the 30a and -34a terms: - (30a - 34a) = -4a

Combine the -10b and -17b terms: - (-10b - 17b) = -27b

Therefore, the simplified expression is -4a - 27b.

I hope this helps! Let me know if you have any further questions.
