Answer 1

$2(x+4)=30\\\\Divide\ by\ 2\ on\ both\ sides.\\\\x+4=15\\\\Subtract\ 4\ on\ both\ sides.\\\\{\boxed{x=11}$

ANSWER: B

Answer 2

If you would like to solve the equation 2 * (x + 4) = 30, you can calculate this using the following steps:

2 * (x + 4) = 30
2 * x + 2 * 4 = 30
2 * x + 8 = 30
2 * x = 30 - 8
2 * x = 22    /2
x = 11

The correct result would be B. 11.
