Is this your way of saying thank you?

HEH?

Just. HEH?

The third term of (2x-1)^6 is... something so long it puts thomas the tank engine to the size of a quark.

It's: (64x^6)-(192x^5)+(240x^4)-(160x^3)+(60x^2)-12x+1

I'm not adding that. I just won't. It is not something I will do.

That's the most I can do. I needed to eat 3 advils. I had a witch doctor see into my brain and she had a stroke and died. The 3 gummy vitamins in my system are not enough. You should pay for my psychiatric bills. You caused it. You're the root of all evil. 

ok maybe im just annoyed.

Yay...!

Huh this is new. I'm not a cryptology person myself but I'm sure we could find an expert on this ever-expansive site.

(Doesn't cryptology involve riddles and encoding messages? The most I know about those are the Caesar and Kryptos)

Yay!

My dearest sire, Sir Pavlov XXXII hath answered to thine call for help.

Sincerely,

Varxaax

Yay!

I think you mean simultaneously by 2, 5, and 10, right?
If so:

Then every number with units digit of 0 from 10 to 10000. 

We can do the equation 10,000/10.

That means 1,000 such numbers.

Yay!

Find out how many cubes have paint, and subtract that from 125.

Thank you so much how do you like?

edit: i got 36

well good explaintion

Using the first equation, we see that x=10-y. 

Plug that in for x in the second equation, and solve!

:)

You could do that, it definately works. If following your way, we would use the difference of squares. But, that would be long and messy.

Instead, we can say that x^2=y, and swap y^2 for x^4.

We get y^2=-4.

So, y is -2i and 2i.

Now, we see that x^2 is -2i and 2i. After solving, the final answers are: x=1+i, x=-1-i, x=-1+i, x=1-i

:)

Thanks!

Let's create a variable for x^2. We can store that as y.

So, our new equation is y^2+y+1=0.

From here, we see that y is y=(−1−i√32)/2,(−1+i√32)/2.

Then, square root the two roots, and you will get the answer!

You did good GS....it is just that the median is   x + 13     (the 14th number in the 27 number sequence )

USe distance formula

(2a-4)^2   +  (a-4 - -1)^2   =  (2 sqrt10)^2

4a^2 - 16a + 16    +  a^2 -6a +9  =  40

5a^2 - 22a -15 = 0       quadratic formula shows    a = 5   or    -  0.6       you can take it from here  

Whoever helps me, thanks.

Try substituting all of this into the distance formula first and expand. See where you can go from there.

EletricParlov, can you help??? I don't know how to explain this :(

good job, looks like i was a little off...

Well from the diagram 3x-9 and 93 must add up to 180. So 3x-9=180-93 --> 3x-9=87. We solve for x to get 3x=96-->x=32.

I don't see a range for x exactally, I only see one value. But, to find that value, we will solve this equation:

3x-9=180-93 (180 degrees in a straight line)

3x=180-93+9

3x=96

x=32.

I only see 32 as an option for x. Is there something I'm missing?

EP, can you help?

Square roots of negative numbers will have "i"  in them. \(\sqrt{-1}=i\). So the square root of a negative number would be the square root of the number if it were postiive with an i.

Remember     sqrt (-1) = i  ?

3 + sqrt (-16)   = 

3 + sqrt (16*(-1) )   =   3 + 4i      

      and   6-sqrt(-64) = 6 - 8i          take it from here ............

Try  a = 1,   b = 2,   c =3
