Replace every x you see with 5 and do the math.

f(x) = 2x^2 + 2x - 3

f(5) = 2(5)^2 + 2(5) - 3

f(5) = 2(25) + 10 - 3

f(5) = 50 + 10 - 3

f(5) = 60 - 3

f(5) = 57

The first one is the correct one.
RT=12 units
TU=6 units
RS=24
T is the midpoint of the line RS.
So, RT is half of the line, so now you have to add the rest of the line to make it equal to 24. 

Have a nice day :D
