Someone came into my shop and stole $100.00 from the register without my knowledge. the person came back in with the same $100.00 five minutes later and he bought $70.00 worth of items and gave him back $30.00 in change. how much money did i lose?

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
