HI!!

OpenStudy (julia):

hey! :)

OpenStudy (misty1212):

did you do \[\sqrt{35^2-21^2}\]?

OpenStudy (julia):

yes

OpenStudy (misty1212):

oh then it is right

OpenStudy (misty1212):

another way is to remember the famous 3 - 4 - 5 right triangle if you multiply all by 7 you get 21 - 28 - 35

OpenStudy (misty1212):
