Answer 2

Simplifying the Expression Using Commutative and Associative Properties of Addition and Multiplication

To simplify the expression (16 + a) * 4 using the commutative and associative properties of addition and multiplication, we can follow these steps:

1. Apply the Distributive Property: The expression can be simplified using the distributive property, which states that a(b + c) = ab + ac.

2. Rearrange the Terms: By rearranging the terms and applying the commutative property of addition and multiplication, we can simplify the expression.

3. Perform the Calculations: After rearranging the terms, we can perform the necessary calculations to simplify the expression.

Let's go through the steps to simplify the given expression.

Applying the Distributive Property

The expression (16 + a) * 4 can be simplified using the distributive property as follows: ``` (16 + a) * 4 = 16 * 4 + a * 4 ```

Rearranging the Terms

We can rearrange the terms using the commutative property of addition and multiplication: ``` 16 * 4 + a * 4 = 4 * 16 + 4 * a ```

Performing the Calculations

Now, we can perform the calculations to simplify the expression: ``` 4 * 16 + 4 * a = 64 + 4a ```

Therefore, the simplified form of the expression (16 + a) * 4 is 64 + 4a.

This simplification is based on the application of the distributive property, commutative property of addition and multiplication, and the subsequent calculations.
