Sum of two values of n if |n – 2| = 10:

This question tests the understanding of absolute value equations. The absolute value of a number represents its distance from zero, meaning |x| = a implies x = a or x = -a.

• Correct Answer: 4. For the equation |n - 2| = 10, there are two possibilities: either n - 2 = 10 or n - 2 = -10. Solving the first, n = 10 + 2 = 12. Solving the second, n = -10 + 2 = -8. The sum of these two values of n is 12 + (-8) = 4.
• Distractors: Options A (2), C (10), and D (12) represent incorrect calculations or individual values of n rather than their sum.
