Answer: 4 hours
Step-by-step explanation:
Let the number of hours that the repair take be represented by h.
Since the cost of Sam's car repair is $20 an hour plus $180 for parts and the total cost was $260, this can be formed into an equation as:
180 + 20h = 260.
20h = 260 - 180.
20h = 80
h = 80 / 20
h = 4
The repair took 4 hours
The value of x is or
Step-by-step explanation:
The expression is
To complete the square, the equation is of the form
The constant term c can be determined using,
Rewriting the expression and factoring the trinomial, we have,
Taking square root on both sides, we get,
Either,
or
Thus, the value of x is or

In order to find the product of two complex numbers their magnitudes are multiplied and their arguments(measure of angles) are added up.
For z₁
Magnitude = 4
Argument = π/3
For z₂
Magnitude = 3
Argument = 2π/5
So, the product of z₁ and z₂ will be:
