Answer:
z = 9
Step-by-step explanation:
36/4 = 9
(f+g)(x) = x^2 -2x +6x + 4
(f+g)(x) = x^2 + 4x + 4
(f+g)(x) = (x + 2)^2
(x + 2)^2 = 0
x + 2 = 0
x = -2
answer
B. -2
Since each barber works 8 hours per day, it means that the barber shop conducts 112 haircuts in 8 hours. This means that it conducts
![\cfrac{112}{8} = 14](https://tex.z-dn.net/?f=%20%5Ccfrac%7B112%7D%7B8%7D%20%3D%2014%20)
cuts per hour. Every barber can conduct two haircuts per hour. This means that a generic number
of barbers conducts
cuts per hour. But we already know that the shop conducts 14 cuts per hour, so the number of barbers is given by
![2b = 14 \iff b = \cfrac{14}{2} = 7](https://tex.z-dn.net/?f=%202b%20%3D%2014%20%5Ciff%20b%20%3D%20%5Ccfrac%7B14%7D%7B2%7D%20%3D%207%20)
