**Modeling equivalent expressions worksheet :**

Worksheet on modeling equivalent expressions is much useful to the students who would like to practice problems on "Equivalent expressions".

**Problem 1 :**

Consider the two expressions 3(x + 2) and 3x + 6 and answer the following questions.

**Questions :**

(i) Model each expression using algebra tiles.

(ii) How many x tiles and 1 tiles does the expression 3(x+2) have ?

(iii) How many x tiles and 1 tiles does the expression 3x+6 have ?

(iv) Is the expression 3(x + 2) equivalent to 3x + 6 ? Explain.

**Problem 2 :**

Consider the two expressions 2(x + 3) and 2x + 3 and answer the following questions.

**Questions :**

(i) Model each expression using algebra tiles.

(ii) **How many x tiles and 1 tiles does the expression 2(x+3) have ? **

(iii) **How many x tiles and 1 tiles does the expression 2x+3 have ? **

(iv) Is the expression 2(x + 3) equivalent to 2x + 3 ? Explain.

**Problem 1 :**

Consider the two expressions 3(x + 2) and 3x + 6 and answer the following questions.

**Question (i)**

**Model each expression using algebra tiles. **

**Answer :**

**Question (ii)**

**How many x tiles and 1 tiles does the expression 3(x + 2) have ? **

**Answer :**

From the above model of 3(x + 2), we have three x tiles and six 1 tiles.

**Question (iii)**

**How many x tiles and 1 tiles does the expression 3x + 6 have ? **

**Answer :**

From the above model of 3x + 6, we have three x tiles and six 1 tiles.

**Question (iv)**

Is the expression 3(x + 2) equivalent to 3x + 6? Explain.

**Answer :**

Yes; each expression is represented by three "x" tiles and six "1" tiles.

**Problem 2 :**

Consider the two expressions 2(x + 3) and 2x + 3 and answer the following questions.

**Question (i)**

**Model each expression using algebra tiles. **

**Answer :**

**Question (ii)**

**How many x tiles and 1 tiles does the expression 2(x + 3) have ? **

**Answer :**

From the above model of 2(x + 3), we have two x tiles and six 1 tiles.

**Question (iii)**

**How many x tiles and 1 tiles does the expression 2x + 3 have ? **

**Answer :**

From the above model of 2x + 3, we have two x tiles and three 1 tiles.

**Question (iv)**

Is the expression 2(x + 3) equivalent to 2x + 3 ? Explain.

**Answer :**

No; 2(x + 3) is represented by two "x" tiles and six "1" tiles. 2x + 3 is represented by two "x" tiles and three "1" tiles.
