We need to solve for x, we need to get x alone

Lets start by removing -5
Add 5 on both sides


Now to isolate x , we need to remove the square from x
To remove square , take square root on both sides

square and square root will get cancelled

So
and 
Answer : C
we need to the value of f(–1)
Table is given in the question
From the table ,
f(x) = 4 when x= -5, that is f(-5) = 4
f(x) = 0 when x= -1, that is f(-1) =0
f(x)= -1 when x=6, that is f(6) = -1
f(x)= -3 when x=9, that is f(9) = -3
So, the value of f(–1) = 0

Answer:
C. 
Step-by-step explanation:
The rectangular form of a complex number is represented by the following formula:
(1)
Where each coefficient can be determined as function of the polar components:
(2)
(3)
Where:
- Magnitude of the complex number, dimensionless.
- Direction of the complex number, measured in radians.
If we know that
and
, then the rectangular form of the number is:




The rectangular form of
