Question

1)-(2х+4). 2)3(х-7). 3)-5(х+4+у)

Answer 1

1) - 2 * ( х + 2 )

2) 3 х - 21

3) - 5 х - 20 - 5 у

Answer 2

To simplify the given expressions, let's apply the distributive property and perform the necessary calculations.

1. (2x + 4) * 2: Applying the distributive property, we multiply each term inside the parentheses by 2: 2x * 2 + 4 * 2 = 4x + 8

Therefore, (2x + 4) * 2 simplifies to 4x + 8.

2. 3(x - 7): Applying the distributive property, we multiply each term inside the parentheses by 3: 3x - 3 * 7 = 3x - 21

Therefore, 3(x - 7) simplifies to 3x - 21.

3. -5(x + 4 + y): Applying the distributive property, we multiply each term inside the parentheses by -5: -5x - 5 * 4 - 5y = -5x - 20 - 5y

Therefore, -5(x + 4 + y) simplifies to -5x - 20 - 5y.
