Step-by-step explanation:

To multiply out brackets, you multiply the values within the bracket by the one outside one at a time.

For example, for the first one, you would do 2*a, which is 2a, then 2*3, which is 6. Since the 3 was positive, the answer would be 2a+6.

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
