A businessman models the number of items (in thousands) that his company sold from 1998 through 2006 as N(x) = −0.1x3 + x2 − 2x + 9 and the average price per item (in dollars) as P(x) = 0.3x + 7, where x represents the number of years since 1998. Enter a polynomial R(x) that can be used to model the total revenue for this company.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
