Answer:
168/(x² +7x)
Step-by-step explanation:
The height of each window is 14/(x+7), and the width of each window is 12/x. The area of each window is the product of its height ans width:
area = (14/(x+7))(12/x) = 168/(x(x +7))
area = 168/(x² +7x)
_____

Option D is wrong, because at 30 min the number of sprays is 2.
rate = 2 sprays/30 min or ²/₃₀ sprays/min
