Answer 2

no sorry

Answer 3

Okay, this is pretty easy. They give you the formula h^2+5h=295, replace H answer in the formula. Such as 17.36^2+5(17.36)=295, then solve it. If the answer on each side of the equal sign doesn't match up then that isn't the answer.

Answer 4

okay thanks so you just keep replacing it each time till you get 295 correct

Answer 5

Or approximately that number. I already know the answer to the problem, so just let me know which one you think it is when you figure it out, and I'll let you know if it's correct :) okay?
