I believe the answer is A. I'm not too sure though. How did I come to this conclusion? ¯\_(ツ)_/¯
Answer:
48 plants.
Step-by-step explanation:
On one side there would be 21 * 12 inches / 21 inches =- 12 plants.
There are 4 sides so that makes 48 plants.
It means that x value is between 2 to 7 ( more than 2, but less than 7)
In notation, 2 < x < 7 or (2,7).
