The area of a rectangle with width 3x is given by the expression 12x² - 15x. write a polynomial expression for the length of the rectangle. (hint: area of a rectangle is length*width)

the area of a triangle with height 4x is given by the expression 16x² - 4x. write a polynomial expression for the base of the triangle. (hint: area of a triangle is 1/2base*height)
