Answer 1

To rearrange the terms using the commutative property and then simplify the expression $8ab-2b+ab-b$, you can follow these steps:

1. Rearrange the expression: $$8ab+ab-2b-b$$

2. Combine like terms:

   • First, combine the terms with $b$: $$-2b-b=-3b$$
   • Now, the expression becomes: $$8ab+ab-3b$$

3. Combine the $ab$ terms: $$8ab+ab=(8+1)ab=9ab$$

Now, we combine everything: $$9ab-3b$$

So, the final simplified expression is: $$9ab-3b$$
