Can you tell me the answer I will give you a medal? @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 :-)

D @Nnesha
Nnesha
  • Nnesha
how ??
anonymous

I don't get this it's between A and C but how do you do this? @Nnesha
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
  • Nnesha
how did you get C ? it's B ?? how did yo uget B ??
Nnesha
  • Nnesha
or D or A how did you get ???
Nnesha
  • Nnesha
4 times n = ?? 4 times -64 = ??? n is same as 1n so multiply the coefficient (4 times 1)n = ?
anonymous
  • anonymous
I knew it, it was B but then you said it wasn't right
Nnesha
  • 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
  • Nnesha
alright B \[\huge\rm \frac{ 1 }{ 4n -256 }\] first 4 times -64 = Negative 256 so how did you divide 256 by 4 ?

Can you help me with one more please then I will give you a medal? @Nnesha
Nnesha
  • Nnesha
what about this one?
anonymous
  • anonymous
I already did it @Nnesha
Nnesha
  • Nnesha
what u got ?
anonymous
  • anonymous
B @Nnesha
Nnesha
  • Nnesha
no
anonymous
  • anonymous
What? @Nnesha
anonymous
  • anonymous
I am Confused rn? @Nnesha
Nnesha
  • Nnesha
yes right expression should be equal to \[\frac{ 1 }{ 4n -16}\] so that's how B isn't correct
anonymous
  • anonymous
Then can you please tell me the answer I will give you a medal @Nnesha
Nnesha
  • Nnesha
if B is incorrect then try another one :-)
anonymous
  • anonymous
What about D? @Nnesha
Nnesha
  • Nnesha
\[\frac{ 1 }{ 4(n-4) }\] distribute parentheses by 4
Nnesha
  • Nnesha
D: is it equal to 1/4n-16 ??
anonymous
  • anonymous
Nooo it's A @Nnesha
Nnesha
  • Nnesha
solve that let me know what you get
anonymous
  • 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
  • Nnesha
divide by which 4 ? and 4 times -4 = what ?
anonymous
  • anonymous
The 2nd 4 @Nnesha
Nnesha
  • Nnesha
\[\frac{ 1 }{ 4(n -4) } = \frac{ 1 }{ 4 \times n - 4 \times 4 }\]
anonymous
  • anonymous
Do you know the answer? @Nnesha
Nnesha
  • Nnesha
yes
anonymous
  • anonymous
Can you please tell me? @Nnesha
Nnesha
  • Nnesha
4(n-4) = ??? 4n and -4 times 4 =?
Nnesha
  • Nnesha
no i want you to learn it!!!
anonymous
  • anonymous
-16 @Nnesha
Nnesha
  • Nnesha
yes right so it is \[\frac{ 1 }{ 4n -16 }\] there is nothing to divide with
anonymous
  • anonymous
You can divide 16/4? @Nnesha
Nnesha
  • Nnesha
how ??? 16 is at the denominator
anonymous
  • anonymous
ohhhh then what's the answer? @Nnesha
Nnesha
  • Nnesha
\[\frac{ 16 }{ 4} <-->divide~~~~~~\frac{ 4 }{ 16 }\] that's the division
Nnesha
  • Nnesha
you know the answer :-)

C @Nnesha

  • Nnesha
reread my comments please !!
Nnesha
  • Nnesha
which option we just solved & got 1/4n -16
anonymous
  • anonymous
I did already @Nnesha
Nnesha
  • Nnesha
so what's the answer?
anonymous
  • anonymous
A @Nnesha
Nnesha
