Answer 1

-m+n
-4e+13
4e-13
18a-90
-5x+5y-35
-39v^2-130v
-42s-46s-12

Answer 2

I will help you with half of them and you can try the rest.

1. -(m - n)

First: use distribution > take the (-) sign and multiply it by m and -n:

= -m - (-n)

Second: two negative become a positive (+):

= -m + n

2. -(4e - 13)

= -4e - (-13)
= -4e + 13

3. -(-4e + 13)

= -(-4e) - (13)
= 4e - 13

4. -6(-3a + 15)

= -6(-3a) - 6(15)
= 18a - 90

5. -5(x - y + 7)

= -5x - 5y - 5(7)
= -5x - 5y -35

Answer 3

Just remember that a minus sign outside parentheses goes with both things in side and changes both their signs.

So in 24 - (6r - 12) for example

the 6r becomes negative and the minus 12 becomes plus 12

So it's 24 - 6r + 12

or 36 - 6r

Answer 4

I won't answer them, but I will give you the distributive property:
a(b+c)=ab+ac
Remember that a negative in front of the brackets is like having -1.

Answer 5

-(m-n) = n-m
-(4e-13) = 13-4e
-(-4e+13) = 4e-13
Do you see the pattern?

Answer 6

Dude, that's a lot.
