Find the length of the 3rd side of each right triangle.

Simplify. Assume that all variables are nonnegative.

{ this means square root

If I get any of these wrong, can someone please show me how to them correctly ?

1. Reiny

good job, I agree with all of them

1,2,3,4,5,6,7 are ok.
8. sqrt (3x^2) = x*sqrt(3) Check that.
9,10,11 ok.
12.
sqrt(3)*sqrt(27) = sqrt 3*sqrt(3*9)
9*sqrt(9) = 9*3= 27. Check that.

check 15. I think you just wrote it wrong. I get 1/5*sqrt(10). Check that.
The others look ok.

I goofed on 12. It's ok.

Thank you both!

I agree with DrBob

I should have checked them a bit less superficially.
