the_rev Posted January 7, 2004 Author Share Posted January 7, 2004 K. There probably easy, but I don't know how to do them, cause I'm stupid. When am I ever gonna have to use math in the priesthood? A rectange is three times as long as it is wide. If it's length and width are both decreased by 2cm, it's are is decreased by 36 cm squared. Find it's original dimensions. The answer is 15cm by 5 cm, now how in the world do you get that? Link to comment Share on other sites More sharing options...

Circle_Master Posted January 7, 2004 Share Posted January 7, 2004 A rectange is three times as long as it is wide. If it's length and width are both decreased by 2cm, it's are is decreased by 36 cm squared. Find it's original dimensions. so if L is the length and W is it's width and A is it's area W*3W = A - that is the original rectangle (W-2)*(3W-2)=A-36 according to your question. now substitute in A (W-2)*(3W-2)=W*3W-36 now do your algebra part.

the_rev Posted January 7, 2004 Author Share Posted January 7, 2004 Ahh, I don't care, as long as I try to do it I get the points so I did it to the best of my ability, and I have gone through my notebook, and circled the problems I need help on, so I can go in to my favorite math teacher that I don't have, to have him explain it than that weirdo teacher that never explains it!

jasJis Posted January 7, 2004 Share Posted January 7, 2004 I will share you what a great math teacher once taught me. I was once a number idiot. I now work with numbers in spread sheets all day for my job, and have for years. I can write formulas that will stun you. It's surprisingly easy. -Always have lot's of paper. -Write out EVERYTHING. Don't try to be all neat and stuff like a Math book. Draw pictures. Writing is your friend. -Never do more than 1 problem on a sheet of paper and only write on 1 side of the paper. -Do not erase. Put a line through it. -God gave us trees to make more paper. (It was a Catholic high school) People envision abstractions differently. When you are unafraid to write out what you are thinking, you learn to organize your thoughts. I almost failed Algebra. The next year I was well on my way to failing Geometry. She taught me this. I then had one of the best grades in the class. Math was then easy for me to learn. I can do word problems now that would give most people brain hemmorages, but it may take 5 sheets of paper. Othertimes when I'm stumped, after I start writing it out, the whole thing falls into place. Write it out. Paper and pencil are your friends.
