Spoiler: So why did the chicken cross the road



LOOK AT ME!

The outer dimension of a closed wooden box are 10cm by 8cm by 7cm. Thickness of the wood is 1cm. find the total cost of the wood required to make the box if 1 cubic centimeter of wood costs $ 2.00/-. i'd do this by doing the sides one and a time, like as if you are building it. maybe do the bottom ...

U get d^2=(2b-b)^2+(a-b)^2=b^2+a^2-2ab+b^2=2b^2-2ab+a^2 d^2=(2b-a)^2+(a-0)^2=4b^2-4ab+a^2+a^2=4b^2-4ab+2a^2 d^2=(a-b)^2+(0-b)^2=a^2-2ab+b^2+b^2=2b^2-2ab+a^2 U can see wat U get when U add! the above translates into d^2=(2b-b)^2+(a-b)^2=b^2+a^2-2ab+b^2=2b^2-2ab+a^2 d^2=(2b-a)...

This is where I ask my algebra teacher questions.

\color{red}(y^3\,-\,y^2\,+\,y\,+\,3)\,\div\,(y\,+\,1) The answer is \color{blue}y^2\,-\,2y\,+\,3 Me and my ex-math teacher got together and figured this question out, however we are not sure how :confused: . Can you please list the steps so that I can see how it is done. Thanks. :D ...

Will you ever allow "Ranks" on here?

I use another phpBB based forum that has ranks... Its just cool to see what rank other people are.
