Guys, please help me with this problem. Thnks.

x^2+4x+5/2
substitute all the x for 3
3^2+4(3)+5/2
simply
9+12+5/2
26/2
13
Answer: The answer is 13
Step-by-step explanation:
first it tells you that x=3 which means that you need to put a 3 in for every x you see in the equation
which will bring you to 3^2+4(3)+5 all divided by 2
3 to the 2nd is 9, 4 times 3 = 12 so 9+12+5 =26 divided by 2 equals 13 :)
