Evaluating Expressions with Algebra Tiles

What term is represented by the algebra tiles?

• 6

• -6

• 6x

• -6x²

Combine like terms. (Green tiles are "x" and yellow tiles are"1")

• 5x + 6

• 11x

• 11

• 6 - 5x

Look at the model. Which of the following algebraic expressions could it represent?

• 5x - 1 + 2x + 3

• 5x + 5 +2x + 3

• 5x + 1 + 2 + 3

• 5x - 1 + 2x + 3x

Look at the model. Which of the following algebraic expressions could it represent?

• -3 + 3x + 6 + 4x

• -3 + 3x + 6 - 4x

• -3 + 3x + 6x - 4x

• -3 + 2x + 6 + 4
