Mini-lesson on A-APR 1 and 3

$$2x^2\ -\ 2x\ -\ 2$$  

$$2x^2\ -\ 2x\ +\ 4$$  

$$2x^{3\ }-3x^2\ +\ 4x\ -6$$  

$$2x^{3\ }-15x^2\ +\ 22x\ -24$$  

$$2x^{3\ }+\ 6x\ -\ 6$$  

$$2x^3\ -18x\ -2$$  

$$2x^{3\ }+\ 9x^2\ -22x\ +\ 6$$  

$$2x^{3^{\ }}+\ 15x^2-14x\ +\ 6$$  

The total area of the storage closet is $$\left(8x\ +\ 10\right)\ ft^2$$  

The area of section A can be represented by the expression $$\left(x\ +2\right)\left(3x\ +\ 3\right)ft^2$$  

The expression $$\left(2x^2\ +\ 1\right)ft^2$$  represents the area of section B.

If x=4, the total distance around the entire storage closet would be 42 ft.

If additional square footage were added to the top right hand corner of the storage closet to to create a standard rectangle, the additional area would be represented by the expression $$2x\ ft^2$$  .
