Question

help.

Answer 1

You have apparently posted this same set of questions before under a different user name. Is that true? If so, why two different user names?

In every situation like this, I ask the student to post ONE question at a time. I think I've asked you to do that.

I'm always glad to help when someone puts honest effort into finding the solution to a problem AND shows the work already done.

Answer 2

there is no need to show work cause it doesn't ask me to show my work.
