Question

Use algebra tiles to model the expression. Then, use the model to help you write an equivalent expression, and complete the statements.

3(x + 1)

 

Model the expression as 123x groups of x + 1.

 

 

There are 123x x tiles.

 

 

There are 1236 + 1 tiles.

 

 

The equivalent expression is 4x3x + 13x + 33x + 4.
