Answer:
I. x = -4 and II. x = 12
Explanation:
For this problem, you would simply need to plug in the values and see if the inequality is true, and if it is, it is a solution, so let's go through the options.
Plugging in x = -4 gives us: -4 < 12 which is true since negative four is less than positive twelve, so this is a solution.
Plugging in x = 0 gives us: 0 < 12 which is true since zero is less than twelve, so this is a solution.
Plugging in x = 12 gives us: 12 < 12 which is false since twelve is not less than twelve but is rather equal to it. if the less than symbol had a line under it, it would also include values equal to it in which case x = 12 would be a solution but since it doesn't, this is not a solution.
Plugging in x = 13 gives us: 13 < 12 which is false since thirteen is not less than twelve but is rather greater than it, so this is not a solution.
