Let 2n,2n+2,and 2n+4 be three consecutive even intgers.write the inequality that represents the verbal senten

Solve the inequality
15.the sum of 3 consecutive even integers is less than or equal to 18
16.the sum of three consecutive even integers is more than 66
17.the sum of three consecutive even integers is less than-12

2n + (2n+2) + (2n+4) <= 18
6n +6 <= 18
6n <= 12
n <= 2

2n + (2n+2) + (2n+4) > 66
6n + 6 > 66
6n > 60
n > 10

2n + (2n+2) + (2n+4) < -12
6n < -18
n < -3
