in brainly if you ask questions, the points are taken from your total and given to the one who answered it..
so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
i think the answer is b.
not 100% sure though.
the correct answer is d
