The doctor told eduardo to take 25 milliliters of medicine the first day. after that, eduardo should take 5 millimeters of medicine three times each day. how many liters of medicine will eduardo take in 10 days?

0.16 Liters

Step-by-step explanation:

First Day = 25 ml

"5 millimeters of medicine three times each day" -- this means 5*3 = 15 ml per day for each of next 9 days

So in first 10 days, first day is 25 ml and each of the 9 days, 15 ml per day. So:

In 10 days, Eduardo will take 160 ml of medicine. To get our answer in Liters, we divide it by 1000, so we have:

So, 0.16 Liters

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
