Answer 2

To expand the given expressions, you need to apply the distributive property, which states that when you have a number outside the parentheses multiplied by an expression within the parentheses, you distribute the number to each term inside the parentheses. Let's expand each expression step by step:

1. (x + y - 2) * 3 Distribute 3 to each term inside the parentheses: = 3 * x + 3 * y + 3 * (-2) = 3x + 3y - 6

2. 4 * (m - p - n) Distribute 4 to each term inside the parentheses: = 4 * m - 4 * p - 4 * n = 4m - 4p - 4n

3. -8 * (a - b - c) Distribute -8 to each term inside the parentheses: = -8 * a + 8 * b + 8 * c = -8a + 8b + 8c

4. (2x - y + 3) * (-2) Distribute -2 to each term inside the parentheses: = -2 * 2x - (-2) * y - 2 * 3 = -4x + 2y - 6

So, the expanded expressions are:

1. (x + y - 2) * 3 = 3x + 3y - 6
2. 4 * (m - p - n) = 4m - 4p - 4n
3. -8 * (a - b - c) = -8a + 8b + 8c
4. (2x - y + 3) * (-2) = -4x + 2y - 6
