Think of imaginary numbers on a complex plane as coordinates - take the real part, that's the x coordinate, the imaginary part that's the y coordinate.
Therefore, for the first blank, -1+3i lies in the shaded area, because its coordinates are (-1,3).
And following on from that for the second one, -4i does not lie in the shaded area, since its coordinates are (0,-4).
Tl;dr is taking a complex number a+bi and placing it on a complex plane, it will have coordinates (a,b)
(2*3)^2
do the parentheses because of using PEMDAS
P= Parentheses
E= Exponents
M= Multiplication
D= Division
A= Addition
S=Subtraction
(2*3)=6
6^2
6*6 ( write out 6 two times because of the exponent)
Answer: 6*6=36
2.5
Explanation: x is a number being multiplied by 2 so if the answer needs to be 5 then 2.5 times 2 is 5
Answer:
D
