Uma Thurman , by Fall Out Boy

I can move mountains
I can work a miracle, work a miracle
Oh, oh, keep you like an oath
May nothing but death do us part

She wants to dance like Uma Thurman
Bury me till I confess
She wants to dance like Uma Thurman
And I can't get you out of my head

The stench, the stench, of summer s*x
And CK eternity, oh h**l yes
Divide me down to the smallest I can be
Put your, put your venom in me

I can move mountains
I can work a miracle, work a miracle
Oh, oh, I keep you like an oath
May nothing but death do us part

She wants to dance like Uma Thurman
Bury me till I confess
She wants to dance like Uma Thurman
And I can't get you out of my head

I'm not sure, I was wondering the same thing though...

No prob, Solveit.....

Thanks CPhill !

a^m * aⁿ   =  a(m + n)

Example :

7³ * 7⁵  =  7³⁺⁵  =  7⁸

a = 5sin20     and b  = 5cos 20 ........so

5[sin20  + cos20]  ≈ 6.408 ≈ 6.41   =  (C)

stupid asker :D

The distance Solveit gave is correct.....however, the bearing  is given by :

arctan[250/100] = 68.2°  =  S68.2°W   [sometimes also expressed as (180 + 68.2)°  =  248°]

"2nd" button "acos"

yes 

is the bearing 90 degrees?

The asker probably did not know how to expand the brackets :)

i wrote the same at first but why would a person ask that :) 

Solveit, there is no equal sign in the question     

You cannot just add one because you feel like it.                      

 3(x+y) = 3*x+3*y = 3x+3y

That is all you can do to simplify this expression :)

BIG UPGRADE

today is big update day: (during the next hours)

- Better profanity filter to screen out bad words. (let's see how this works in practice)

- Pictures will be screened better to check they are appropriate.

- It is now possible to respond to a specific post within a thread.

- Non-members can no longer give points

- You can no longer give yourself points any more

- Moderators now have the ability to close threads so they cannot be added to.

\(a^2+b^2=c^2\)

\(100^2+250^2=c^2\)

\(\sqrt{100^2+250^2}= 269.2582403567252016\)

Answer:269.3

This looks very involved!     

Thanks Chris and Heureka    :D

Hi everyone, 

It's been a quiet Saturday/Sunday.  Not that many good questions but more than our fair share of nuisance posts that had to be deleted.  

Anyway:

Threre are ALWAYS some good questions and they are ALWAYS accompanied by good and interesting answers.  

Today our industrious answerers are  CPhill, rarinstraw1195, Dragonslayer554, Amberella, asinus, gliu1, BruceWayne, Heureka, Solveit, Geno3141 and Hayley1.

Thank you all for your enthusiasm and your great answers   

Communications:

I will now take this opportunity to talk about this problem of obnoxious posts and posters 

A person who makes these unpleasant posts is looking for a reaction - any reaction!  As soon as you put words into a reply post you are giving this person exactly what they want, you are giving them attention!  If you do not respond at all the person can derive no reaction thrill.  It would feel to him like he is trying to prod a brick wall.  He'll get bored with that very soon and go find a different playground that might be more fun.  

SO PLEASE DO NOT RESPOND AT ALL!

Yesterday I gave a happy belated birthday message to TitaniumRome.  Titanium, InjustaGod and Rarinstraw all expressed their pleasure and the break in the wrap drought.  Thanks guys, Titanium also gave me a peice of his birthday cake.  Since forum cakes are non-diminishing, I would like to share it with all of you.  ENJOY!   

3(x+y)

3x+3y=0

x+y=0

hi galeano,

It is evening for me   LOL

Bob builds a rectangular room inside a building of side length 3(x+2) and width (x-2). He decides to put a rubber surface on the floor of the room. The lengths of the room run parallel. Write an algebraic fraction in simplest form for the fraction of the area of the floor of the shed covered in rubber surface. Show all working out.

I reallydo not understand this quesiton but if the room is  length 3(x+2) and width (x-2)

then the area is   3(x+2) multiplied by (x-2)    units squared

Area = 3(x+2)(x-2)    units squared
