Help please I need to turn this in today

10

Step-by-step explanation:

the formula is a^2+b^2 =c^2

so you do 8x8 which is 64

and 6 x 6 which is 36

then you add them together which is 100 and then you square root that which is 10

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
