To start this, let's create a ratio for the two triangles (the triangle you are trying to find, and the super large triangle). Taking the two  longer sides, we get that the scale is 13/65=1/5. Multiply 60 by 1/5, and we get that '?' is 12.

Let $f(x) = 2x+1$ and $g(x) = f(2x) - 3$. What is $g(g(2))$?

To start this, we see that g(x)=f(2x)-3. So..., we can plug in 4 into f(x). This will give us 9. From there, we subtract 3 and get 6. Repeat the process, but plug in 12 for x in f(x). This will give is 23-3=20. Therefore, g(g(2))=\(\boxed{20}\)

Wheres CPhill on Leaderboard? :(

Press the little arrow on the bottom. Then CPhill will show up on the top. (prob because his score is too high, or he has not been on lots, lol)

To begin this, let's find the slope of that line. The slope is: 15/4. Now, we need to find the y intercept. To do this, we substitute (0,y) for (-8, -6). Solve for the slope (and set it equal to 15/4), and we get 24. Therefore, the equation of the line is y=15/4x+24.

Here is the graph:

I'm have trouble understanding: "where 0". Could you please clarify? Thanks!

Thank you, guest :)

To start this problem, we will first square (a+b+c). This will be, in expanded form, a^2+b^2+c^2+2ab+2ca+2bc=81. Since ab + bc + ca = 26, we can multiply that by two to get 2ab + 2bc + 2ca = 52. Subtract that from our first equation, and we get a^2+b^2+c^2=81-52=29

Let TU and VW be chords of a circle, which intersect at S, as shown. If ST = 3, TU = 15, and VW = 3, then find SW.
