1) 52 + 33= 85
2) 26 + 42 = 68 or 26 - 42 = - 16
3) 72 - 2015 = =1943
4) 32 x 22 = 704
The hypotenuse can be solved by this formula. X^2 = 6^2 +6^2
X^2=64
Usually you cut it down to 8 but it wants the squared form so 64.

I'm pretty sure DEF is a scalene triangle since it looks like none of the sides are equal to each other.
Hope this helps!
