A=48
b=144
c=-84

First, you simplify the second equation by multiplying 6 to 2x and 6 to 7.  Then, you get the two equations, (4x-2) times (12x+42).  You then use the FOIL method, multiplying 4x to 12x, 4x to 42, -2 to 12x, then -2 to 42.  Simplify.  Then number before x squared is your a value, value before x is b, and the value without x is c.

rodikova [14]

Answer: There are 4 average cars in the system.

Step-by-step explanation:

Since we have given that

Arrival rate = λ = 4 cars per hour

Service rate = μ = 5 cars per hour

We need to find the average number of cars in the system.

So, Average number of cars would be

L_q=\dfrac{\lambda^2}{\mu(\mu-\lambda)}\\\\L_q=\dfrac{4^2}{5(5-4)}\\\\L_q=\dfrac{16}{5}\\\\L_q=3.2

So, it becomes,

L=L_q=\dfrac{\lambda}{\mu}\\\\L=3.2+\dfrac{4}{5}\\\\L=3.2+0.8\\\\L=4

Hence, there are 4 average cars in the system.
