Answer 6

Are we just simplifying -4.5[2x - (0.5 - 1.4)]

Answer 7

@sammixboo yeah but i'm stupid and can't figure it out, X~X

Answer 8

OK so to start simplifying -4.5[2x - (0.5 - 1.4)] we do 0.5 - 1.4 which is?

Answer 9

And it's OK. You don't understand it, so I am here to help :)

Answer 10

-0.9?

Answer 11

brb

Answer 12

Right! so now we have


-4.5(2x - (-9))

Now we must distribute the -4.5, so we multiply -4.5 by EVERYTHING in the parenthesis

-4.5 * 2x - (-4.5*-9)

So what is -4.5 * -9 and -4.5 * 2x?

Answer 13

Okie dokie tag me when you are back

Answer 14

-4.5( 2x - (0.5 - 1.4) ) = -9. x - 4.05

Answer 15

batman

Answer 16

back

Answer 17

@sammixboo

Answer 18

\[-4.5 (2 x-(0.5\, -1.4)) \]\[-4.5 (2 x+0.9)\]\[-9. x-4.05 \]

Answer 19

@robtobey i don't get it.....X~X

Answer 20

So continuing where I left at

Now we must distribute the -4.5, so we multiply -4.5 by EVERYTHING in the parenthesis

-4.5 * 2x - (-4.5*-9)

So what is -4.5 * -9 and -4.5 * 2x?

Answer 21

How -4.5*2x just multiply -4.5 * 2 and then throw on that x

Answer 22

-4.5 * -9 is 40.5?

Answer 23

I meant -0.9 sorry

Answer 24

Aaah, so what is -4.5 * -0.9

Answer 25

4.05?

Answer 26

Right, and what is -4.5 * 2x?

Answer 27

-4.5 * 2x - (-4.5*.-9)
-4.5 * 2x - 4.05


To finish simplifying this just multiply -4.5 * 2x

Answer 28

idk what the "x" in it is so, no clue X~X

Answer 29

The x is the variable. To multiply two numbers and one has a variable, just multiply the two whole numbers, then throw on the variable.

So what is -4.5 * 2

Answer 30

-9?

Answer 31

Right, and put the variable x in, so -9x

-4.5 * 2x = -9x

OK so since that equals that, our answer is -9x - 4.05 !

Answer 32

4.5 * 0.9 = 45 * 9 * (0.01) = 405 * (0.01) = 4.05

Answer 33

i don't get it..

Answer 34

-4.5[2x - (0.5 - 1.4)]
-4.5[2x - (-0.9)]
-4.5*2x - -4.5(-0.9)
-9x - -4.5(-0.9)
-9x - 4.05

Answer 35

Distribution gets a little confusing. I was confused when I first learned it

Answer 36

i still don't get it

Answer 37

aaanndd i'm doomed...it's 11:55 where i am and i need to get this done before 12:00
