Answer: C
Explanation:
Sqrt 9 x sqrt 4 = sqrt 9 x 4
To do this problem, you will need to know the side lengths of the triangle. If you have those, just plug them in for a, b, and c and evaluate the square root.
Here is an example. If the sides are 3, 4, 5.
It would be:

The 6 is in the formula because it is the semi-perimeter (half).
Answer:
-4y=40
y=-10
x-3(-10)=17
x-30=17
x=17+30
x=47
