The area of a rectangular blanket in square centimetersis 40x^2+2x-65. The width is 4x-5cm^2. Find the dimensions of the blanket in terms of x.
Can someone plz help with this? I've posted it a few times now!
use a calculater
You know that area=width*height. You are given area and width. so height = (40x^2+2x-65) / (4x-5)
__10x_+ 13______________
4x-5 | 40x^2 + 2x - 65
-40x^2-50x)
____________
52x - 65
-(52x - 65)
Thus the length is 10x + 13 and the length is 4x-5
To check, multiply these together with FOIL

Would you like to tell me how I'm supposed to use a calculator to solve this problem when I have no idea how to even attempt to start solving this probem?!

And how is that mean? It does not help me one little bit to tell to use a calculator. I needed help with the problem and that answer nor yours was helpful. OK
