Question

Quizplus · Accepted Answer

If x represents the first of three consecutive even integers, the next two even integers would be x+2 and x+4. Therefore, the sum of the three integers would be x + (x+2) + (x+4) = 3x + 6. If x is the first of three consecutive even integers, then the next two even integers would be x + 2 and x + 4. The sum of these three integers can be expressed as: x + (x + 2) + (x + 4) = 3x + 6. Therefore, the correct answer is B, 3x + 6.
