Hello!
The answer is: 15 mL
Why?
From the statement we have that 250 mg need to be given every 8 hours, we can calculate how many mg will be given each day (24 hours):

So,
a day
We also know that there are 50 mg cefaclor every 1mL,
So, to know how many mL will be given with 750mg, we just need to divide it by 50

Therefore,
15mL or 750 mg of cefaclor will be given each day.
Have a nice day!
2x^3+x^2-15x factored completely would be: <em>x(x+3)(2x-5).</em> Not sure which answer choice but I hope that I was some help.
Well because 14 is nowhere near half of 950 (which is 475), 1/2 is bigger. I hope this helped.
