Answer 2

To simplify each of these expressions, you can distribute the numbers outside the parentheses to the terms inside the parentheses. Here's how you can simplify each expression:

1. 5(2a+3): Distribute 5 to both terms inside the parentheses: 5 * 2a + 5 * 3 = 10a + 15

2. -3(1-4a): Distribute -3 to both terms inside the parentheses: -3 * 1 + (-3) * (-4a) = -3 + 12a

3. 15(6x-1): Distribute 15 to both terms inside the parentheses: 15 * 6x + 15 * (-1) = 90x - 15

4. -2(3+x): Distribute -2 to both terms inside the parentheses: -2 * 3 + (-2) * x = -6 - 2x

So, the simplified expressions are:

1. 10a + 15
2. -3 + 12a
3. 90x - 15
4. -6 - 2x
