Answer

The model is:

The product is3x2+6x3x2+6x .

1Step-1 – Given

The given expression is3x(x+2) .

2Step-2 – To determine

We have to model the given expression.

3Step-3 – Calculation


Use an x tile and a 1 tile to mark off a length equal to x + 2 along the top.

• Use the tiles to mark off a length equal to 3x along the side.

• Draw lines to show the grid formed.

• Fill in the lines with the appropriate tiles to show the area product. The model

shows the polynomial3x2+6x .


The area of the rectangle is the product of its length and width. Substituting for the length, width, and area with the corresponding polynomials, we find that3x(x+2)=3x2+6x .
