6. The polynomial 2x3 - 13x2 + 17x - 10 represents the volume in cubic feet of a rectangular
water holding tank at Marlon's Farm. The depth of the tank is represented by the
expression (x - 5) feet. The length is 17 feet. Let x represent the width of the tank.
Part A: Write an equation for the polynomial using the dimensions of the tank (V= L x W x H)
Part B: Find the width of the tank.
