9) I'm not really sure how to answer it, but I guess like 2.1, 2.2, 2.5, etc.,
10)
so {5, 6, 7, 8} is the answer
11) for some reason it won't let me insert a picture but put place
above 2, and then place
above 3, and then place
in between 2 and 3, but place it a little closer to three since
12) place
between 2 and three, but closer to two since
and also
and for number 13) the square root of 144 is 12, and the square root of 169 is 13, so any numbers between 12 and 13 will work.
I hope this helped and if not, message me and ill try to explain!
