A rectangular piece of cardboard that is 7 inches by 20 inches has squares of length x inches on a side cut from each corner. (Assume that 0 < x < 3.) Represent the remaining area in the form of a polynomial function A(x).

The remaining area in the form of a polynomial function where  0 < x < 3.

Step-by-step explanation:

Breadth of rectangular piece of cardboard = 7 inches

Length of rectangular piece of cardboard = 20 inches

Area of cardboard =

Area of cardboard =

Area of cardboard =

Squares of length x inches on a side cut from each corner.

Length of square = x

Area of 1 square =

Area of 4 squares =

Area of remaining portion

So, the remaining area in the form of a polynomial function where  0 < x < 3.
