11c + 9d – 9
11c – 9d – 3
7c – 7d – 3
7c – 9d + 3
I need help ASAP.

Answer 1

11c - 9d - 3

Explanation:

First, open the bracket

9c - 8d + 2c - 6 - d + 3

Next, collect like terms

9c + 2c - 8d - d - 6 + 3

Lastly, simplify/ solve

11c - 9d - 3

Done.

Answer 2

11c-9d-3
drag everything out of ( )

9c + 2c = 11c
-8d - d = -9d
-6 + 3 = -3

therefore, 11c-9d-3 is the answer
