Answer 1

-2d+8, but you can also simplify it to -d+4

Answer 2

4-d+(-d-4)
4-d-d-4
4-2d-4
-2d

Answer 3

you forgot a sign jelly

Answer 4

oh lol jk ur right

Answer 5

whoa nellly

Answer 6

\[\large -2d+8\neq -d+4\] the left side is twice the right side

Answer 7

you cannot really see it, but it is 4 - d + -(d-4), it should be 4-d-d+4

Answer 8

there are no equal sides satellite

Answer 9

signs

Answer 10

ummmm nvm then

Answer 11

i'm pretty sure it's supposed to be 4-2d+4, which is -2d+8, simplified would be -d+4

Answer 12

"-2d+8, but you can also simplify it to -d+4"

Please show us how you managed to have -2d+8 simplified to -d+4

Answer 13

Like @satellite73 said, -2d+8 is NOT same as -d+4

Answer 14

agreed

Answer 15

And... where do that 2 disappeared to?

Answer 16

i just told you, those numbers are factors of 2

Answer 17

you can't just remove certain thing completely from expression

Answer 18

yes you can if you can simplify it, take an algebra class and you will see

Answer 19

\(-2d+8 = 2(-d+4)\)

You are the one who need t take algebra. Especially to learn what simplification means and how it works...

Answer 20

Yes, they are factors of 2, but you can't just magically remove it...

Answer 21

look, this terms are factors of 2, you CAN simplify it, ok, take an algebra class

Good luck explain that...

Answer 23

what you are doing is dividing the expression by 2. this is not simplification...

Answer 24

you don't necessarily have to put the 2 outside of the parentheses, you can leave like that called STANDARD FORM, now go to take an algebra class

Answer 25

maybe u should search online?

Answer 26

Ok, I'm go ahead and just stop here and assume you are trolling.
