Simple...
remember A(B+C)=A*B+A*C
You have to have a common factor in both terms..(number)..this number would be 6.
So we know it has to have 6 in your answer.
If we plug n chug..:
20*6+20*5=220
6*40+6*5=270
6*40+6=246
6*4+6*5=54
6*45= 270
This being said, 6*40+6*5 is the choice you need.
Thus, your answer.
