Apparently some did not take me seriously. "Do my work for me" is the same as "Do my homework" in my opinion. I did not understand how the answer was obtained.

I am done with this site.

I don't think this is an answer. Where did 12 come from?

The answer is

[12L - x - na] /[ n + 1] inches.

There are 12 inches in a foot.

There's no point typing to Randy Dandy, he's "done with this site".
