Answer:
C) 4(5c -2d)
Step-by-step explanation:
You would need to find the greatest commen factor in the equation.
it would end up being 4 since it is the biggest number that can divide between 8 and 20.
20/ 4 = 5
8/4 = 2
so you would leave the varibles since you can't take them out and put 4 on the outside of the parantheses.
4(5c -2d)
