the first is a optimization so giving the final dimensions is very important 1)You have 50 cm of wire, and you have to use part of this wire to make a rectangle that's twice as long as it is wide, and the rest of the wire (if there is any left) to make a square. What should the dimensions of the shapes be if you want the total area to be as small as possible? What if you want the total area to be as large as possible? 2) find the point of inflection algebraic for 3x^5-30x^3
