If the two triangles are similar you can use a proportion to solve for the length of the legs.
\frac{2}{4}=\frac{x}{9}
Now, you would cross multiply to get 
4x=18
Now, you simplify that using the division property of equality.
You end up with 
x=4.5
Therefore, the legs of the triangle with a base of 9 inches will each be 4.5 units long.

-8p^2+8p+7=9<br> how do i find the discriminant
m_a_m_a [10]
The discriminant can be found using the formula b^2-4ac 

First put your equation in standard form, where all your values are on one side, and just add f(x) or y in front of your equation. 
y= 8p^2-8p+2

The first value of your equation is a   (a=8)
The second term of your equation is b  (b=-8)
The last term of your equation is c  (c=2)

Plug in the values to the discriminant equation b^2-4ac

The Greek alphabet contains 24 letters. How many fraternity names with Greek letters can be formed if each fraternity name conta
ankoles [38]
For the first letter we have 24 choices. Since letters can't repeat the second letter has 23 choices (24 minus 1 that was used for the first slot) and the third has 22 (24 minus one for the first slot and one for the second slot).

The total number of combinations is thus: 24 x 23 x 22= 12,144
