Suppose X and Y are independent random variables with E(X) = 1 and Var(X) = 5 and E(Y) = 7 and Var(Y) = 3. Find E((2+X)^2) and Var(X-3Y-4)

For the Variance one, it's just Var(X) - 3Var(Y) - 4 right?

The quick question I had was does the square of (2+X) matter at all? Or do I just do (2 + E(X))^2?
