: solve
: A machine produces open boxes using sqaure sheets of plastic. The machine cuts equal sized squares measuring 3 inches on a side from each corner of the sheet, ,and then shapes the plastic into an open box by turning up the sides. If each box must have a volume of 675 cubic inches, find the length of one side of the open box.
: solve
: 4x^(7/2)-8=0
: solve by substitution
: x^(2/3)+2x^(1/3)-8=0
: answers a){-4,2} b){-64,8} c){-8,64} d){-2,4}
