Nickolas, this is way over your head :)

Dah, a circle is actually a special case of an ellipse.

A circle is an ellipse where for foci are the same point.

In a certain hyperbola, the center is at (2, 0), one focus is at (2, 6)  and one vertex is at (2, -3). The equation of this hyperbola can be written as

\(\frac{(y-k)^2}{a^2}-\frac{(x-h)^2}{b^2}=1 \)

Find h+k+a+b

Try looking at this:  

I like LagTho's  addition too about the tringle being upside down  :)

don't forget the units squared, you have to add that!

The area is    6 units squared       

Ok you call it a see saw but the people in the video called it a Teeter Totter.

Anyway, it doesn't matter.  We all know what I was talking about  (I hope lol) 

ok thanks. 

Maybe when I was young you called it a Teeter totter more but now it is changing so that See Saw is more common,

Here in Australia, it has always been a See Saw.

That was just an American you tube clip which definitely called it a Teeter Totter.

anyway, this is what I am talking about.

Thanks,

What country are you in? 

On american TV shows I have heard them call what you and I call a see saw, a teeter totter. ....

Look

You have to add the areas of all 5 sides.

4 triangles and 1 square.

hint:

The area of a triangle is  1/2 * base * height.
