# Writing a polynomial for this box thing

Could someone guide me through this? *math dummy*

Write a polynomial in standard form that models or represents the area of the shaded region.

Thanks!

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.
