Answer:
11. is false
12. is true
Step-by-step explanation:

11 is false and 12 is true
The correct answer is 18.
If X and Y are two sets, then X × Y is the Cartesian product of X and Y, which is the set of all pairs (x, y) such that x ∈ X and y ∈ Y.
This means
A × A = {(1, 1), (1, 2), (1, 3), (2, 1), (2, 2), (2, 3), (3, 1), (3, 2), (3, 3)}
I would say Logan possibly... not entirely sure.
