the area of a triange can be modeled: A(x)=x^3-1. The length is x-1. Find a polynomial to represent the width of the triangle. (the answer is x^2 + x +1 .... how do u get that?)

Is this an equilateral triangle? or an arbitrary triangle?
So the width od the triangel is \(2(x^2+x+1)\)
not sure why the "2" is there.

I guess area of triangle is 1/2*base*height
is the length and width?
can we base and sides?
oops you are right. how could i doubt it?
OMG I MENT RECTANGLE SRY GUYS
lol well i read "rectangle' too so it must have been a subliminal message. then there is no 2!
how is that equal to that?
actually, you are just going to use the formula of the area of a rectangle which is length times width
divide both sides by x-1
then you will get x^3−1
which is equal to x^2+x+1 through factoring its gcf.
