-----
The HA = a/1 = a = 2
----
The VA = -c = -3
----
So a + c = 2+3 = 5

To find the vertical asymptote, set denominator=0, then solve for x:
x+c=0
x=-c=-3 (vertical asymptote)
c=3
..
If degree of numerator=degree of denominator, as in this case:
Horizontal asymptote= quotient of lead coefficient of numerator divided by lead coefficient of denominator.
horizontal asymptote=a/1=2
a=2
a+c=5
