What is the area of the outside box?

What is the area of the inside box?

How would you get the area of the shaded region?
 
|2(x-4)+2(x+3)| - |2(x+2) + 2(x+1)|

I'm actually more confused as to what a polynomial is >_> *cough*
 
A polynomial is a function that only involves powers of the variable x.

However, your real problem is that you are confusing "area" with "perimeter". The area of a rectangle is "length times width", lw, not 2l+ 2w. Also, since all the numbers involved are positive, there is no need for absolute value.
 
LOL thank you so much.

Yes, my main problem with math is that I don't know what most of the terms mean and/or confuse them with other terms...-_-

I need a math dictionary.
