Answer:
4n = B
Step-by-step explanation:
N + N + N + N
Pretend that n is equaled to 2
2 + 2 + 2 + 2 is also equaled to 4 * 2 because there are four 2s.
It is just the same as n + n + n + n = 4 * n
4 * n is also written as 4n which is B.
Lets also look at the other answers.
A does not make sense because 4 + 2 (the example) does not make sense.
C does not make sense because exponents deals with multiplying n and not adding it
D does not make sense because you can already tell using the Distributive property that it is wrong
The answer is b, I hope this helps!
