Please consult the forum rules:
(6) Do not post classroom or homework problems.
Come on now, being new to the board, Im sure you have read the rules! See rule 6 if you havent yet read them. Funny thing is that you dont know how close the answer is to you!! Browse/search the board, the internet, read a book. All of these things are better options than asking for the answer. You will never learn that way.
