If your studying for a maths exam, you should probably do the work yourself, answers are probably in the back of the text book if not , do the questions with answers in the back of the textbook without looking at the answers. Try to figure out the method to solve each one and then use that as a basis to answer these questions once you've checkedthat you did them correctly. If we give you the answers then you won't learn and this will in term not help you in the future when you take higher maths.



All in all good luck..in math the only way to get things right is by doing them yourself so you can understand it, and if you already understand it, then you should have no problem doing them yourself. (:

I totally agree with Nana 0601.

It's good if u do it ur self and u'll improve ur maths. It's not helping you by giving u the answers but the opposite. U should get more practice in maths. try to find a simple way to solve these questions.BTW best of luck.
