Answer:
x = 2, x = -6
Step-by-step explanation:
![x^2+4x-4=8](https://tex.z-dn.net/?f=x%5E2%2B4x-4%3D8)
Subtract 8 from both sides.
![x^2+4x-4-8=8-8](https://tex.z-dn.net/?f=x%5E2%2B4x-4-8%3D8-8)
Simplify.
![x^2+4x-12=0](https://tex.z-dn.net/?f=x%5E2%2B4x-12%3D0)
Solve with quadratic formula.
a = 1
b = 4
c = -12
I do not have time to show work for quadratic formula parts.
I am so sorry for this inconvenience.
Answer:
6 hours
Step-by-step explanation:
Let the labor hours be x.
The bill comprises of parts cost plus labor cost. Labor cost is hours times the cost per hour. Then we have equation:
- 265 + 48x = 553
- 48x = 553 - 265
- 48x = 288
- x = 288/48
- x= 6
So the answer is 6 hours.
