Hi, Laugh123!

If you would like help in solving the homework questions that you have posted, you'll need to show that you've made some attempt at coming up with the answers yourself and then post a question as to what your having trouble figuring out because of already trying to come up with the answers yourself.

If you do that, then someone skilled in the particular subject will be more likely to come along to help you to understand how to solve the questions yourself so that you'll be able to learn the best.
