Many are very similar to each other. We are not here to do YOUR homework....we are here to ASSIST you when you REALLY need help....TWENTY FOUR QUESTIONS ?????
I definitely second EP's comment! This site isn't for just giving you the answer, it's for showing you solutions and ways to think about these problems so you can improve! You have to realize that posting so excessively without giving second thought to the solutions is just a short term solution; it doesn't help you improve at all.
