Answer:
A and D
Step-by-step explanation:
if each van held 6 students and the math club went in two vans, then you can use multiplication to figure it out. each van held 6 students, the math club went in two vans, so the equation can be 6 x 2. BUT you can do addition as well. because 6 plus 6 will give you the same answer as 6 x 2 because each van holds six students, there were two vans so 6 plus 6 is another way to solve this problem.
