Question

Will medal and fan..The equation is below..

Answer 1

\[7x-2[3x(x-y)+6x]\] A.\[11x-6y\] B. \[-11x+6y\] C.\[7x+6y\] D.\[-6x^2-5x+6xy\]

Answer 2

Halp -.-

Answer 3

This is not an equation since there are no equal signs.

Anyways, your first step is to distribute

what is 3x(x-y) equal to when you distribute?

Answer 4

I don't know what you mean.. ;-;

Answer 5

It's important that you include the instructions when you post a problem. What are you supposed to do in this problem?

Answer 6

have you seen the distribution property before? something like

2*(x+3y) = 2*x + 2*3y = 2x + 6y

Answer 7

@mathmale I don't know.. This is how it came.. An yes I've seen that.. Is it 3x^2 -3xy?..v-v

Answer 8

`3x(x-y) ` will turn into `3x^2-3xy`, yes correct

Answer 9

So
`7x - 2[3x(x-y)+6x]`
turns into
`7x - 2[3x^2-3xy+6x]`

Answer 10

now we must distribute the -2 through to each term inside the square brackets

what is ` - 2[3x^2-3xy+6x]` equal to?

Answer 11

-6x(2+x-y)?

Answer 12

-2 times 3x^2 = _____ (fill in the blank)

Answer 13

I'd suggest you be really clear what you're looking for, what you're trying to do, what the question asks. Seeing that there is no = sign in the given expression, I'd venture that the instructions say, "Simplify by combining like terms."

Answer 14

\[-6x^2\] @jim_thompson5910 ?

Answer 15

Expand, and then combine like terms to simplify the following: 7x-2[3x(x-y)+6x]

Answer 16

yes @readergirl12

Answer 17

-2 times -3xy = _____ (fill in the blank)

Answer 18

6xy

Answer 19

yes

Answer 20

-2 times 6x = _______

Answer 21

-12x

Answer 22

So `-2[3x^2-3xy+6x]` turns into `-6x^2+6xy-12x`

Answer 23

which means
`7x - 2[3x^2-3xy+6x]`
turns into
`7x - 6x^2+6xy-12x`

Answer 24

now combine like terms in `7x - 6x^2+6xy-12x`

Answer 25

How is that done?

Answer 26

hopefully you see that 7x and -12x are the only pair of like terms?

Answer 27

Yep.

Answer 28

what would they combine to?

Answer 29

\[x^7 -12x ?\]

Answer 30

idk where you're getting x^7

but I agree with the fact that 7x-12x = -5x

Answer 31

There are no other like terms to combine. So we're done with the problem
`7x - 6x^2+6xy-12x` becomes `-6x^2-5x+6xy`

In the end,
`7x - 2[3x(x-y)+6x]` is equivalent to `-6x^2-5x+6xy`

Answer 32

oh nvm I misread what you wrote. You should have 7x and -12x combine to -5x

since 7-12 = -5

Answer 33

So.. It's 10x or no?

Answer 34

where are you getting 10x ?

Answer 35

Ehhh.. Thought you told me to combine 7x -12x and 5x,Sorry. -.-

Answer 36

oh I see, no once you combine 7x and -12x, those two terms go away and are replaced with -5x

Answer 37

Mkay..Anything else need to be done?

Answer 38

nope, `-6x^2-5x+6xy` is as simplified as it gets

Answer 39

Woooow.. That took longer than I thought..Well Thank youuu Here's your cookie.. ♥♥
