Answer:
9 plants
Step-by-step explanation:
Since we are trying to find the number of plants that are shorter than 9 inches, we will look at the plants that are 2, 3, 4, 5, 6, 7, and 8 inches tall.
Each x counts as a plant
# of 2 inch plants: 1
# of 3 inch plants: 1
# of 4 inch plants: 4
# of 5 inch plants: 1
# of 6 inch plants: 1
# of 7 inch plants: 1
# of 8 inch plants: 0
Add up the number of plants:
1 + 1 + 4 + 1 + 1 + 1 + 0 = 9
Answer:
9 plants
