distribute parentheses by outside term

Can you tell me the answer I will give you a medal? @Nnesha

- Nnesha

distribute = multiply
example
a(b+c)= a times b + a times c
= ab+ac
now try that

Is B the answer? @Nnesha

- Nnesha

how ??
4(n-64) distribute parentheses by outside term
let me know what you get :-)

- anonymous

D @Nnesha

- Nnesha

how ??

- anonymous

I don't get this it's between A and C but how do you do this? @Nnesha

- Nnesha

distribute 2nd parentheses by outside term
for example B |dw:1434213817087:dw|
multiply 4 times n= ??
4 times -64 =?

- anonymous

C @Nnesha

- Nnesha

how did you get C
?
it's B ?? how did yo uget B ??

- Nnesha

or D or A
how did you get ???

- Nnesha

4 times n = ??
4 times -64 = ???
n is same as 1n
so multiply the coefficient
(4 times 1)n = ?

- anonymous

I knew it, it was B but then you said it wasn't right

- Nnesha

i didn't say it's wrong it can be A B C or D
i want to know how did you get the answer ?
DON'T guess!

- anonymous

You Just have to Distribute 4n then you have to multiply 4 times 64 you will get 256 by that you divide 256 by 4 then it will give you 64 so B is your answer @Nnesha

- Nnesha

alright B \[\huge\rm \frac{ 1 }{ 4n -256 }\]
first 4 times -64 = Negative 256
so how did you divide 256 by 4 ?

- anonymous

Can you help me with one more please then I will give you a medal? @Nnesha

- Nnesha

what about this one?

- anonymous

I already did it @Nnesha

- Nnesha

what u got ?

- anonymous

B @Nnesha

- Nnesha

no

- anonymous

What? @Nnesha

- anonymous

I am Confused rn? @Nnesha

- Nnesha

yes right expression should be equal to \[\frac{ 1 }{ 4n -16}\]
so that's how B isn't correct

- anonymous

Then can you please tell me the answer I will give you a medal @Nnesha

- Nnesha

if B is incorrect then try another one :-)

- anonymous

What about D? @Nnesha

- Nnesha

\[\frac{ 1 }{ 4(n-4) }\]
distribute parentheses by 4

- Nnesha

D: is it equal to 1/4n-16 ??

- anonymous

Nooo it's A @Nnesha

- Nnesha

solve that let me know what you get

- anonymous

Distribute 4n and distribute 4 times 4 then it gives you 16 after that you divide it by 4. So the answer will be 1/4(n-4) So the answer is A @Nnesha

- Nnesha

divide by which 4 ?
and 4 times -4 = what ?

- anonymous

The 2nd 4 @Nnesha

- Nnesha

\[\frac{ 1 }{ 4(n -4) } = \frac{ 1 }{ 4 \times n - 4 \times 4 }\]

- anonymous

Do you know the answer? @Nnesha

- Nnesha

yes

- anonymous

Can you please tell me? @Nnesha

- Nnesha

4(n-4) = ???
4n and -4 times 4 =?

- Nnesha

no i want you to learn it!!!

- anonymous

-16 @Nnesha

- Nnesha

yes right so it is \[\frac{ 1 }{ 4n -16 }\]
there is nothing to divide with

- anonymous

You can divide 16/4? @Nnesha

- Nnesha

how ???
16 is at the denominator

- anonymous

ohhhh then what's the answer? @Nnesha

- Nnesha

\[\frac{ 16 }{ 4} <-->divide~~~~~~\frac{ 4 }{ 16 }\]
that's the division

- Nnesha

you know the answer :-)

- anonymous

C @Nnesha

- Nnesha

reread my comments please !!

- Nnesha

which option we just solved & got 1/4n -16

- anonymous

I did already @Nnesha

- Nnesha

so what's the answer?

- anonymous

A @Nnesha

- Nnesha

yes

- anonymous

Thanks:) @Nnesha
