Answer 6

First, you have to find set D.
All of the numbers that are divisible by 3 from 1 to 12 are 3,6,9,12.
So, D={3,6,9,12}.

Answer 7

Now, for the first problem, we can notice that 6 and 12 are 2 common elements for C and D.
So the correct set operation to get {6,12} would be intersection, or ∩.
If we write that in an equation, C∩D={6,12}

Answer 8

For the second problem, we can see that all of the elements from C and D are mashed up in one set. We use union, denoted as U.

If we write that in an equation, \[C \cup D= {2, 3, 4, 6, 8, 9, 10, 12}\]

(I forgot the curly brakets for C∪D.)
