Answer:
12,600mg per 21 days
Step-by-step explanation:
200mg three times a day → (200mg)(3) = 600mg per a day
21 days → (21)(600mg) = 12,600mg per 21 days
Answer: B
Begin by simplifying the given equation, so it's rearranged into standard form. Move all the terms onto one side, so they equal 0. This would result with 
-3x-9=0. Quadratic formula is (-b±√(b²-4ac))/(2a). Standard form follow this variable format: 
+bx+c. Use the numbers that correspond with each variable to substitute them into the quadratic formula. This would be
(-(-3)±√(-3²-4(4)(-9)/2(4).
Hello from MrBillDoesMath!
Answer:
Leftmost graph: x<= -2 or ( minus infinity, -2]
Middle graph: (-5, infinity)
Right graph: (-2, 3)

n the graphs the white circle means that value is NOT included in the set. For example, In the Right graph the values -2 and +3 (the "endpoints") are NOT included in the solution set.
In graphs ")" means the value is NOT included but "]" (the square bracket) means the value IS included.
