DAmon you equaled them to zero that is not rightt An open-topped box can be made from a rectangular sheet of aluminum, an open-topped box can be made from a rectangular sheet of aluminum, with dimensions 40 cm by 25 cm, by cutting equal-sized squares from...

what do you mean by intervals

but its an inequality

ya but they are inequalities 1512<x(40-2x)(25-2x)<2176 it does not equal 1512 it is bigger than it hence this (<)

so wouldnt it be 4x^3 - 130x^2 + 1000x - 1512 > 0 instead of equalling

oh wait never mind damon sorry

but why are you testing numbers between 2 and 4

on never mind sorry lol

but is it two graphs s or one
