Using the perimeter of the rectangle, it is found that she should buy at most 16 plants.
---------------------------
The perimeter of a rectangle of length l and width w is given by:

In this question, the perimeter is of 1 ft by 4.5, thus,
, and the perimeter is:

- Perimeter of 11 ft.
- The plants will be at least 8 inches = 2/3 feet apart along the perimeter, thus:
1 plant - 2/3 ft
x plants - 11 ft
Applying cross multiplication:




At least 8 inches apart(can be more), thus she should buy at most 16 plants.

Answer:A on edge
Step-by-step explanation:
Answer: 3x+8y=100
x+y=20
x=12
y=8
Step-by-step explanation: x would represent the number of multiple choice questions and y would represent the number of short response questions. the multiple choice questions were 3 points meaning that you need to find x. the short answer response questions were 8 points meaning you need to find y. altogether you need to get 100 points. for the second equation you have 20 questions that need to be both multiple choice and short response. therefore the second equation would be x+y=20. if you solved this, the answer would be that x equals 12 and y equals 8. hope this helped! :))
