The domain for f(x) and g(x) is the set of all real numbers. let f(x)=3x+5 and g(x)=x^2 find (f+g)(x) a. x^3+5 b. 3x^2+5 c. 3x^3+5x^2 d. x^2+3x+5

Hello from MrBillDoesMath!

Choice C

Discussion:

(f+g)(x) = f(x)        + g(x)

           = (3x + 5) + x^2

          = x^2 + (3x + 5)  by the commutative property

which is choice D

Thank you,

MrB

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)
