An architect is designing a new building. He makes a model of the building such that the area of the rectangular base is 12x2 - 11x - 5 and the length is 3x + 1. The completed model will be in the shape of a rectangular prism where the volume is given by the polynomial 24x3 - 58x2 + 23x + 15. Determine the width and height of the model in terms of x. Fill in the values of m and b to complete the expressions. Type the width on the first line and the height on the second line.
