Mathematics
1 answer:
vovangra [49]2 years ago
4 0

Answer:

A. n = 5

Step-by-step explanation:

S = n² + n

When S = 30:

                                                       n² + n = 30

Subtract 30 from both sides:  n² + n - 30 = 0

Factorize:                               (n - 5)(n + 6) = 0

Therefore                                                 n = 5 or -6

As n > 2, then n = 5 only
