Q. Evaluate the expression for

j = -6

.

\newline

Write your answer as a decimal or whole number.

\newline

12 + 1.2j =

_____

Identify Expression: Identify the expression to be evaluated. $\newline$ We are given the expression $12 + 1.2j$ and we need to substitute $j = -6$ into this expression.
Substitute $j = -6$ : Substitute $j = -6$ into the expression. $\newline$ Replace $j$ with $-6$ in the expression to get $12 + 1.2(-6)$ .
Perform Multiplication: Perform the multiplication. $\newline$ Calculate $1.2$ multiplied by $-6$ to get $-7.2$ . $\newline$ $1.2 \times -6 = -7.2$
Add to $12$ : Add the result to $12$ . $\newline$ Now, add $-7.2$ to $12$ to get the final result. $\newline$ $12 + (-7.2) = 4.8$
