Step-by-step explanation:

  • Well, h+2h+h=4h, so it isn't equal to 3h. Do not select that one.
  • 2(6g+2g)=12g+4g=16g, and it is equal to 16g. Select that one.
  • 3(4j)=12j, so it isn't equal to 7j. Do not select that one.
  • 5k+2k=7k, so it isn't equal to 10k. Do not select that one.
  • 7m+7m+7m=21m, and it is equal to 21m. Select that one.
