Expand the expression

3(x+4)

6(2x+3)

2(7+6x)

To expand an expression, you simply distribute the number outside the parentheses to each term inside the parentheses.

1. Expanding 3(x+4):

Multiply 3 by each term inside the parentheses:
3(x + 4) = 3 * x + 3 * 4

Simplify each term:
= 3x + 12

Therefore, 3(x+4) expands to 3x + 12.

2. Expanding 6(2x+3):

Multiply 6 by each term inside the parentheses:
6(2x + 3) = 6 * 2x + 6 * 3

Simplify each term:
= 12x + 18

Therefore, 6(2x+3) expands to 12x + 18.

3. Expanding 2(7+6x):

Multiply 2 by each term inside the parentheses:
2(7 + 6x) = 2 * 7 + 2 * 6x

Simplify each term:
= 14 + 12x

Therefore, 2(7+6x) expands to 14 + 12x.
