Rewrite in simplest terms: minus, 9, a, minus, 2, left parenthesis, 9, a, minus, 5, right parenthesis−9a−2(9a−5)

The expression \(-9a - 2(9a - 5)\) can be simplified as follows:

1. Distribute the \(-2\) across the terms inside the parentheses:  
   \(-9a - 2(9a - 5)\)  
   = \(-9a - 2 \cdot 9a + 2 \cdot 5\)  
   = \(-9a - 18a + 10\)

2. Combine like terms:  
   \(-9a - 18a + 10 = -27a + 10\)

So, the simplified form is:
\[
-27a + 10
\]

Here are 5 related questions:
1. How would the expression change if the \(-9a\) term were positive?
2. How do you distribute when the sign outside the parentheses is positive?
3. What if the number inside the parentheses was more complex, like \(9a + 3b - 5\)?
4. How can you factor the final simplified expression \(-27a + 10\)?
5. Can you solve the equation if \(-27a + 10 = 0\)?

**Tip**: Always distribute carefully and combine like terms to simplify expressions easily.
