Artemon [7]

The correct answer from the choices given will be -13 - 4i. The numerical part is the real number while the term containing i is the imaginary part.

A complex number is one that both a real and an imaginary component, both of which are preceded by the letter I which stands for the square root of -1.

\rm 13 + 4 i + n =0

By transfeering the left-hand side term to the right-hand side the sign will change. We will get the value of n as;

\rm n=-13 - 4i

Hence the correct answer from the choices given will be -13 - 4i.

for 15 hourse, just multiply $12 by 15 because per hour means per 1 hour
15 times $12=$180

No, the probability of getting a 5 is 1/6, but you could roll any number of fives in a row. It is just as likely to get rolled the second time as it was the first.
