try taking it one step at a time and multiplying each set one by one. watch the negative signs! remember: a negative times a positive is negative, and a negative times a negative is positive!
2m(m+n4)= 2m^2 2mn+8m
next:
5(2m+2n) = 10m+10n
next:
n(m+4n5) = nm + 4n^25n
you're left with
2m^22mn+8m10m+10n+nm+4n^25n
now, add "like terms" (aka terms that have the same letters and powers, like 10n and 5n)
So,
2m^2nm2m+5n+4n^2
is your answer! (answer choice C.)
