B. (a+3)^2= a^2+ 6a+9 (a+3)= a^3+ 6a^2+9a+3a^2+18a+27= a^3+ 9a^2++27a+27 - ---------------------------------

Of course girl! Algebra is my thing :)
The correct answer is B, and here's why:
(a+3)^3 is the same as (a+3)(a+3)(a+3)
(a+3)(a+3)=a(a+3)+3(a+3) (distributive property)
a^2+3a+3a+9=a^2+6a+9
And from there we see that all the values match. Hope this helps
