Answer:
A. d ≤ –7 or d > 8.
Step-by-step explanation:
Given  : 2d + 3 ≤ –11 or 3d – 9 > 15.
To find : What are the solutions of the compound inequality .
Solution : We have given 2d + 3 ≤ –11 or 3d – 9 > 15.
For  2d + 3 ≤ –11 
On subtracting both sides by 3
2d  ≤ –11 - 3 .
2d  ≤ –14.
On dividing both sides by 2 .
d  ≤ –7.
For  3d – 9 > 15.
On adding both sides by 9.
3d > 15 + 9 .
3d > 24 .
On dividing both sides by 3 .
d > 8 .
So, A. d ≤ –7 or d > 8.
Therefore,  A. d ≤ –7 or d > 8.
