               - 5y  - 5y
         -3x - 3y > 9
 -3x + 3x - 3y > 3x + 9  
                -3y > 3x + 9

-3x+ 2y > 5y+ 9
⇒ -3x > 5y -2y+ 9
⇒ -3x > 3y+ 9
⇒ x < (3y+ 9)/(-3)
⇒ x < -y -3

The inequality equivalent to -3x+ 2y > 5y+ 9 is x < -y -3~

Use the Pythagorean theorem a^{2} + b^{2} = c^{2} to find the missing side length of a right triangle 

In this case, after you plug in the given numbers your equation is 12^{2} +  y^{2}  =  20^{2}

Then, Just solve that equation for y.

144 +  y^{2} = 400

x^{2} = 256

\sqrt{} y^{2}  =  \sqrt{256}

y = 16

So the answer is B, 16 cm.

I hope this helps, please feel free to ask questions if you're still confused :)
