Answer:
B, C, and D are all equivalent to 3(4h+2k)
Explanation:
We use the distributive property to say 3(4h+2k)=12h+6k
"A" distributes to 12k+6h
"B" distributes to 12h+6k
"C" distributes to 6k+12h (associative property works)
"D" is already distributed to 12h+6k
So A is wrong, and B, C, and D are right
Hope this made sense!
