Your answer did make some things clearer :D Thanks!
 

However, when subtracting 8 from x=4, wouldn't that get you x=-4? Sorry if I sound clueless... 

Let's do this, Guest! :D :D

First, we can find the zeros of this inequality.

That would be

x=3 or x=-4

To make this greater than zero, the answer would have to be greater than -4 but less than 3, (If more than three, that would get us a negative number! Yikes)

So, our answer would be -4

This can also be written as x>-4 AND x<3.

Hope this helped!

Please please let him just be on one of his long vacations.... :(

I think it's because he wasn't online for awhile.. kind of like what happened to Rom's before.

Total possible arrangements for the six books: 6! or 720

Places for Conrad's books are:

First book: 7 possible places

Second book: 6 possible places

Third book: 5 possible places

If we multiply that together, we'll get the total number of permutations! 

So, our answer is 720 * 7 * 6 * 5 or 151200.

I think this will be the same as this rule:

(a+b)(a-b)=a^2-b^2

So, our answer will be

1/cos a minus sin a/cos a

It happens when users aren't active for awhile, right?

Nooooo! CPhill come back!

Let's say "the number" is x.

1/4x=3 times 19

1/4x=57

--Multiply 4 to each side--

x=228.

Now find 1/6 of 228.

228 times 1/6 = 38.

So our answer is 38

You can try drawing a 3 by 3 grid and a 6 by 6 grid. Try counting the lines you drew

Stopped by here and saw this!
