- 2/5 - 5/8i
- 2 + 3i
- -1.5 + 17i
Step-by-step explanation:
A real number is a number that exists in real life.
An imaginary number is a number that doesn't exist, hence it has the letter i in it.
A complex number consists of a real number and an imaginary number.

Gotta analyze the answer
then go and multiply them both thats what i think
C . 250 cm^2
cause its the same
Answer: 128 
Step-by-step explanation:
Let the width be W then the length will be 2W since it is twice as long as it width.
The formula for calculating the perimeter of a rectangle is given by :
P = 2 ( L + W )
48 = 2 ( W + 2W )
48 = 2(3W)
48 = 6W
Divide through by 6
Therefore:
W = 48/6
W = 8 inches
This means that the Length is 2 x 8 = 16 inches
Area = Length x breadth
Area = 16 x 8
Area = 128 
The formula for the area of a cylinder is 
×h
First, we do not have to worry about pi because we are leaving our answer in terms of it so we can move on to the radius squared.
The radius is halfway across a circle so our radius would be 4 and we have to square that and we will get a product of 16.
Lastly, we have to multiply 16 by 8 because 8 is the height of the cylinder
16 × 8 = 128
Therefore, the volume of the cylinder would be 128
