# Normal Distribution times constant

I can't seem to find anything about this on the web. If I have a random variable distributed Normally:

x ~ Normal(mean,variance)

is the distribution of the random variable still normal if I multiply it by a constant, and if so, how does it affect the mean and variance?

Thank you Dason, that was exactly what I needed.

Regarding what the mean E(.), and variance, var(.), can you work out these??
$$E(aX)=??$$
$$Var(aX)=??$$
