Answer:
He has 4 more to hang
Step-by-step explanation:
13 total; you must add the 5 he already hung in the morning plus, the 4 he hung in the afternoon; leaving you with 4 because 5 plus 4 is 9. 13 minus 9 is 4.
When you buy a coffee table or piece of circular furniture
N=25 because 20 divided by 4 is 5 which is 1/5 of n meaning 5x5 is 25
