Answer:
B, C, D
Step-by-step explanation:
First, we need to find what 4(4a+5) is. Using the distributive property we can see that it is 4*4a+4*5 or 16a+20. B clearly is one of the answers. C is also one of the answers because 12a+4a+20 adds up to 16a+20. Finally, 2(8a+10) does indeed result to 16a+20, so it is all B,C, and D.
