Answer 2

It seems like you've provided a list of mathematical expressions, and you'd like me to simplify them. Let's go through each of them one by one:

a) -(a + 5) - c: To simplify this expression, distribute the negative sign: -(a + 5) - c = -a - 5 - c

6. -15 + (-a - b + c): To simplify this expression, you can add the numbers and variables together: -15 + (-a - b + c) = -a - b + c - 15

B) d + (a - 17 + b): To simplify this expression, you can remove the parentheses and combine like terms: d + (a - 17 + b) = d + a + b - 17

r) -(--v - 8) - 21: To simplify this expression, first deal with the double negative: -(--v - 8) - 21 = -(v + 8) - 21

Now, you have simplified each of the given expressions. If you need any further clarification or assistance, please let me know.
