Prime numbers that can be added or substracted to obtain -19 are:

-17 and -2.

This factors into

(x-17)(x-2) which would be the same as

x^2-19x+34.

So, k=34.

(With Latex)

\(t-27=4t\)

\(-3t-27=0\)

\(-3t=27\)

\(t=-9\)

You mean if you can ask science? I guess, since this is a "scientific calculator" site 

Actually Melody, I prefer this 

The square root of 16, as Guest said, would be 4 and -4.

Note that (-4)^2 and 4^2 both equal 16 :)

Let's plug the values in!

f(17)=50

f(50)=149

f(149)=446.

So, f(f(f(17))) would equal 446.

We can see that every loli is equal to 2 dollars :)

So what we can do is 126 * 2 which is 252.

You'll make $252 :)

I assume you mean something like f(x)=1+k equations or something like that, Guest. Correct me if I'm wrong please ;)

These are kind of like two variable equations; f(x) usually represents y or another variable.

You can replace the f(x) as another variable, like y=1+k to make it easier.

However, if it is f(k), that means you plug in the value of k given.

For example: f(k)=1+k, k=1. This is the same as f(1)=1+1=2.

Oh, okay, I get it! 

can you read this? :)

Welcome :D (Nice hearts, by the way)
