Which of the following expressions are equivalent to 3(4h + 2k) ?

nordsb [41]

Answer:

B, C, and D are all equivalent to 3(4h+2k)

Step-by-step 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!
