Which Is equivalent to 8s + 20t by the distributive property

Question

A. 4 (2s + 5t)

B. 4 (2 + 5t)

C. 8s (1 + 3t)

D. 8 (s + 20t)

Answer 1

Hello Eniya, I'll go with A.

When you expand by distributing the 4, you get 4 times 2s plus 4 times 5t.

 

B is wrong because the 2 is missing an s. There are no "8" constant terms in your 8s + 20t.

C is wrong because 8s distributed with second term 3t is 24st - again not in the 8s + 20t goal.

D is wrong because 8 distributed with second term 20t is 160t - this does not match your goal.

 

Good luck, TV
