7)2x(3y+-6)=???
10.)5x-3x+2xy+31x+-18xy=??
5.)3/4(12x+16)
7.)(16+13x)10
2.)8(3m+4n
8.)(14+7a) 1/7

Answer 1

Whats the question?

Answer 2

those are the questions...

Answer 3

oh.rewrite into simplest terms using distributive property???????

Answer 4

Haha betterrrr...Ok, one second.

Answer 5

if you're helping pleaseee go in order of how I posted them.... thnx(:

Answer 6

Ill do each one starting from the top:

\[-\frac{2}{3}(c-12)=-\frac{2}{3}*c-\frac{2}{3}(-12)=-\frac{2c}{3}+8=8-\frac{2c}{3}\]

The second has "\(\pm\)". Is that intentional?

Answer 7

+- is intentional.. on the one u did jw if the answer is 8-2c/3????

Answer 8

Yeah?

Answer 9

ok thanks, imworking out your problem onn my worksheet..

Answer 10

\[2x(3y+-6)=2x(3y-6)=(2*3*x*y-2*6*y)=6xy-12y\]

Answer 11

wait please

Answer 12

on #3. 2c/3=8 cant u multiply the 3 times 8 to simplify that further because I think it can go down further?????

Answer 13

Nooo, because you had the expression \(-\frac{2}{3}(c-12)\). There was no equals sign in the first place. Where did that one come from haha

Answer 14

on one of the past lessons I think it was order of operations pemdas the teacher said we can always multiply denominator iwasnt sure if these problems were the same my baddddd... I got 3 and 7 now.. pleaseeee help w/10

Answer 15

Alright!

Answer 16

10.\[\eqalign{&\phantom{=.}5x-3x+2xy+31x-18xy \\&=2x+2xy+31x-18xy \\
&=2x+31x+2xy-18xy\\
&=33x-16xy}\]
...not much simplifying to do

Answer 17

Tell me when your ready for next

Answer 18

ok ready.. THANKS soooo much for help (:

Answer 19

No problem :) happy to help:
\[\eqalign{& \phantom{=.}\frac{3}{4}(12x+16) \\
&=9x+12 \\

}\]

Answer 20

Sorry im answering a lot of questions at the same time lol

Answer 21

7 pleaseeee

Answer 22

is #7 multiplied by 10 or is it to the tenth power ?

Answer 23

\[10(13x+16)=130x+160\]

Answer 24

No, its a question on distributive property. Multiplication. That would be a really pain that one eh?

Answer 25

I got 130x+160 because 10(16)=160 am I right?

Answer 26

Yes!

Answer 27

please help w/2 and 8.. and then I have 5more similar questions pleaseeee stay on here though):

Answer 28

Alright!

Answer 29

\[8(3m+4n)=24m+32n\]

Answer 30

ok I understood that one.. please help w/8 ad then 5 more

Answer 31

\[\frac{1}{7}(14+7a)=2+a\]

Answer 32

23.)5xy(-2x)(-3y)
27.)-15a(4b)(2bc)
24.)7a(-4ab)(2a)
26.) -cd(5c)(-7cd)
28.) 7x(-9xy)(-8y)

Answer 33

your hes veryyyyyyy much appreciated.. (:

Answer 34

\[5xy(-2x)(-3y)=30x^2y^2\]

Answer 35

\[-15a(4b)(2bc)=-120ab^2c\]

Answer 36

\[7a(-4ab)2a=-56a^3b\]

Answer 37

\[-(cd)(5c)(-7cd)=35c^2d^2\]

Answer 38

\[7x(-9xy)(-8y)=504x^2y^2\]

Answer 39

DONE! haha I got to go.
