Answer:
985.15mg
Step-by-step explanation:
Calculation for how many milligrams of the drug should he receive every 12 hours
First step is to calculate the weight in kg
255 lbs = 255/2.2 = 115.9 kg
Second step is multiply mg/kg in order to get total medicine per day
Dose per day=115.9kg × 17 mg 
Dose per day= 1,970.3
Third step is to calculate how many milligrams of the drug should he receive by dividing the day dose by 2 
Dose milligrams=1,970.3/2
Dose milligrams=985.15mg
Therefore how many milligrams of the drug should he receive every 12 hours will be 985.15mg
 
        
             
        
        
        
Answer:
x= -3     x = 1/2     x=-2
Step-by-step explanation:
f(x)=(x+3) (2x-1)(x+2)
Set equal to zero
0 =(x+3) (2x-1)(x+2) 
Using the zero product property
x+3 =0   2x-1 =0    x+2 =0
x= -3    2x =1       x = -2
x= -3     x = 1/2     x=-2
