Answer:
A
Step-by-step explanation:
If we distribute the 3 to the equation in the parenthesis, we end up with this
12h + 6k
Now, let's do the same thing for the other two equations
3(2k + 4h) = 6k + 12h
You can rearrange this equation to look like 12h+ 6k, making it the exact same as 3(4h + 2k).
So A is equivalent
How about B?
3(4h + 2h) = 12h + 6h = 18h
18h does not equal 12h + 6k, so B is not equivalent
