Make each known side into a ratio like so...
75/6 
(Because 75 is the shadow casted by the building, and 6 is the shadow casted by sarah)
and 50/x 
(50 is how tall the building is and sarah's height is what needs to be found) 
Therefore, 
75    50
----  -----
 6      x

Do cross products;
50 x 6 = 75 x X
300 = 75x 
Divide by 75 
x = 4ft

-3(x - 3) > 5 - 5x
use the distributive property

-3x + 9 > 5 - 5x
subtract 5 from both sides

-3x + 4 > -5x
add -3x to both sides

4 > -2x
divide both sides by -2 to isolate x

x > -2

The correct answer is D. x > -2.
