If f(x) = 3^2and g(x)=x+2, find (f •g)(x).
ОА. 3x^2 +6х
ОВ. 3х^3 +6х
Ос. X^3 + 2
OD. 3x +6x^2

Step-by-step explanation:

(f •g)(x)= 3x² * (x + 2)

            = 3x²*x + 3x² *2

            =3x³ + 6x²

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75
