    Welcome to the PF, huda123.

    Please take care not to give out answers to homework/coursework questions. It is against the PF Homework Help rules. Please see the "Rules" link at the top of the page.

    Please instead provide hints, or clarifying remarks, and be tutorial in your help here. Our goal is to help the original poster (OP) to figure out the problem on their own. After all, that is how they will learn the material the best.
