Answer:
60(2 + 5)
Step-by-step explanation:
The factors of 120 and 300 have many different combinations but that is not our primary focus, we can simply distribute every answer to see which is correct.
2(60 + 15)
(2(60) + 2(15))
120 + 30
This is not 120 + 300, therefore incorrect.
40(3 + 7)
(40(3) + 40(7))
120 + 140
This is not 120 + 300, also not incorrect.
60(2 + 5)
(60(2) + 60(5)
120 + 300
This is equal to 120 + 300, therefore correct.
