Answer:

5(x+4)(x+8)

Step-by-step explanation:

5x^2+60x+160

factor out the 5 first,

5(x^2+12x+32),

then factor out the trinomial,

find 2 numbers that when they multiply,

you get the third term, which is 32 in this case,

and when they add up,

you get the second term, which is 12 in this case.

5(x+4)(x+8)

You are to give an injection of a drug. The dosage is 0.4 mg per kilogram of bod The concentration of the drug in vial is listed

kipiarov [429]

Answer:

You inject 60.9628 milliliters of dosage

Step-by-step explanation:

1 pound = 0.453592kg,

Patient's weight in pounds = 168

Patient's weight in kg = $76.2035 kg$

Now we are given that The dosage is 0.4 mg per kilogram of bod

So, dosage = $0.4 \times 76.2035 mg = 30.4814 mg$

1 microgram = 0.001 mg

Concentration of drug = $500 micrograms/ml = 500 * 0.001 mg/ml = 0.5 mg/ml$

Now we are supposed to find How many milliliters (= cc) are you to inject?

So,milliliters of dosage required to inject = $\frac{30.4814}{0.5} = 60.9628$

Hence you inject 60.9628 milliliters of dosage
