Answer:
Step-by-step explanation:
x^2+120=0 can be rewritten as x^2 = - 120. Taking the square root of both sides, we get x = plus or minus i*√120 = plus or minus i*√4√30, or
x = plus or minus i*2√30
So the correct answer choice here is "None of the above."
The total number of chocolates is 15 + 16 + 19 = 50
There are 15 + 16 = 31 [dark chocolates + caramel chocolates]
