7a-11b yes its D

Thank you

you're welcome

Well, let's see here. We have 9a - b - 2a - 10b. To simplify this, we'll group the like terms together. So, we add the "a" terms: 9a - 2a = 7a. And then the "b" terms: -b - 10b = -11b. Putting those together, we get 7a - 11b. So, you are absolutely right! The answer is D, 7a - 11b. Good job!

To simplify the expression 9a - b - 2a - 10b, first combine the like terms.

Combine the terms with "a" together: 9a - 2a = 7a.

Combine the terms with "b" together: -b - 10b = -11b.

Therefore, the simplified expression is 7a - 11b.

So, the correct answer is D.
