Select all expressions that are equivalent to (2n + 6)(n + 3)
we have
(2n + 6)(n + 3)
apply distributive property
2n^2+6n+6n+18
2n^2+12n+18
Verify each option
option A
2(n^2 + 6n +9)=2n^2+12n+18 -------> is ok
option B
is not correct
option C
is correct
option D
is not correct
option E
2(n + 3)(n + 3)= (2n + 6)(n + 3) ------> is correct
option F
2(n + 3)^2=2(n^2+6n+9)=2n^2+12n+18 -----> is ok
therefore
