Answer:
B. (x-2)^2=12
Step-by-step explanation:
The constant that completes the square is the square of half the coefficient of the x-term. That value is (-4/2)^2 = 4.
There is already a constant of 2 on the left side of the equal sign, so we need to add 2 to both sides to bring that constant value up to 4.
x^2 -4x +2 = 10 . . . . . . . given
x^2 -4x +2 +2 = 10 +2 . . . . complete the square (add 2 to both sides)
(x -2)^2 = 12 . . . . . . . . . write as a square
4’1= 4 feet and 1 inch
12 inches= 1 ft.
12(4)= 48 ; 48+ 1inch = 49 inches
1’10= 1 foot and 10 inches
1(12)= 12 + 10 = 22
49-22= 27 inches !

Answer:</h2><h2>
The total cost (C) charged by the internet service provider = $65 + $18(n)</h2>
Step-by-step explanation:
Initial fee charged by the servic eprovider = $65
Cost per hour of labor for office internet installation = $18
The cost per hour be $18
Cost per two hours = 18 * 2 = $36
Cost per n number of hours = $18 (h)
where h represents the number of hours
The total cost (C) charged by the internet service provider = $65 + $18(n)
