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.

Step-by-step explanation:

All those x values are in the domain. In order to show your work, just show yourself plugging in those numbers.

You get 9, 0, and 1
