I did the wrong homework sheet, so now I have to have this sheet finished tonight. I was off school for a few days so I missed some of the explanations given on how to do everything, and I'd appreciate some help. It's three questions I'm stuck on... I'm sure they'll look easy to other people; I've seen topics on here what are wayy advanced to what I'm doing. Sorry, I'm rambling. Here're the questions.







Thanks so much if you can help! I was really worried before I found this forum. >_<
