Use the distributive property to expand the linear expression.

3(4x + 3)

To expand the linear expression 3(4x + 3) using the distributive property, you need to distribute the 3 to both terms inside the parentheses.

This results in:
3 * 4x + 3 * 3

Simplifying this further:
12x + 9

Therefore, the expanded form of the linear expression 3(4x + 3) is 12x + 9.

To expand the linear expression 3(4x + 3) using the distributive property, you will multiply 3 by each term inside the parentheses separately.

Step 1: Multiply 3 by 4x:
3 * 4x = 12x

Step 2: Multiply 3 by 3:
3 * 3 = 9

Therefore, the expanded form of the linear expression 3(4x + 3) is:
12x + 9

To use the distributive property to expand the expression 3(4x + 3), you need to multiply the 3 by each term inside the parentheses.

First, distribute the 3 to the first term, which is 4x:
3 * 4x = 12x.

Next, distribute the 3 to the second term, which is 3:
3 * 3 = 9.

Therefore, the expanded form of the expression 3(4x + 3) is:
12x + 9.
