Answer:
A. 7
B. -3
C. 8
D. 13
E. 5a+17
F. 
+ 8a + 20
Step-by-step explanation:
A. f(1) = 5*1 +2, which equals 7
B. f(-1)= 5(-1)+2 which equals -3
C. g(-3)= (-3)^2+ 2(-3)+ 5 = 9- 6+ 5 = 8.
D. g(2)= (2)^2+ 2(2)+ 5= 4+ 4+ 5= 13.
E. f(a+3)= 5(a+3)+2 = 5a+ 15+ 2= 5a+ 17.
F. g(a+3)= (a+3)^2+ 2(a+3)+ 5= + 6a+ 9+ 2a+ 6+ 5= + 8a+ 20.

distributive property is when you take the number on the outside of the parenthesis and you, well, distribute it to the inside numbers.
so
35(5 + 7)
you have to do 35 * 5 and 35 * 7
its 175 and 245, and then you add those to get 420
same with 12
12 * 6 and 12 * 5
that's 72 and 60
72 - 60 = 12
you minus cause in the parenthesis it's a minus symbol in this case
please thanks if this helped or if u need more help just ask me
