Answer:
6(4c-3), 9w-1
Explanation:
GCF is the biggest thing you can divide both 24c and 18 by.
you can see that you can divide both 24c and 18 by 6, and when you do that you get 4c and 3. That means that the answer for that question is
6(4c-3) (which is A)
The next question all you need to do first is distribute the 3/4 to the 12w and 8.
3/4 * 12w = 9w
3/4 * 8 = 6
so you get
9w -6 + 5
you combine like terms to get
9w - 1 (B)
