Answer: 6, 12, 18, and 24
Step-by-step explanation: all you have to do is see what times 2 equals something that also 3 times something else
ex:
2 x 3 = 6 3 x 2 = 6
2 x 6 = 12 3 x 4 = 14
2 x 9 = 18 3 x 6 = 18
2 x 12 = 24 3 x 8 = 24
i hope that this makes some kind of sense even though im not good at explaining things.
