Answer 1

C is the correct answer hope it helps

Answer 2

Answer: You have the correct answer. It's choice C.

=========================================================

Work Shown:

`3n^2+5 = -46\\\\3n^2 = -46-5\\\\3n^2 = -51\\\\n^2 = -51/3\\\\n^2 = -17\\\\n = \pm√(-17)\\\\n = √(-17) \ \text{ or } \ n = -√(-17)\\\\n = √(-1*17) \ \text{ or } \ n = -√(-1*17)\\\\n = √(-1)*√(17) \ \text{ or } \ n = -√(-1)*√(17)\\\\n = i√(17) \ \text{ or } \ n = -i√(17)\\\\`

where
`i= √(-1)` is the imaginary number.

The quadratic formula is another option you could do and you should get the same answers as above.
