Note that x is the hypotenuse of a right triangle. Applying the Pyth. Thm.,

x^2 = 2^2 + 6^2, or x^2 = 4 + 36 = 40.

Thus, the hypotenuse is +sqrt(40), or 2sqrt(10).

I am building a fence in my backyard. I have 120 nails, and I need to put 4 nails

You'll be able to put 4 nails thirty times.
You put them every 6 feet
So, you have 5 feet before running out.
