3. 5x-2
4. -3x+15
5. -4x-28
6. -4x+ 12
7. 8x+ 40
To find the answer you need to multiply the number outside of the parentheses by each number/variable in the parentheses.
For example, number 9 says 8(-x-6) you would have to "distribute" the 8 out the both the variable and the number.
8 multiplied by -x is -8x because a negative times a positive is a negative and 8 multiplied by -6 is -48. So there for your answer would be -8x-48

You have to make sure to also remember the multiplying rules:
positive times a positive= positive
positive times a negative= negative
negative times a negative= positive
( i hope this helped! i don't do all of them bc there is quite a lot but yeah!)

I am very confused with this. This is a algebra 1 question x-2x-2=-(x+4)-4

Answer:

-3=x

Step-by-step explanation:

First you must add the X's on each side which gives you: 1x-2= -x - 4 - 4

Next you must add the first number 4 to the - 2 on the other side.

Then you do the exact same thing with the other number 4.

After that you get 1x+6=-x, then you subtract the 1 x with the -x to get 6= -2x.

Finally divide both sides by 2 and your final answer is -3 = x
