Answer:
x = 2 x = -6
Step-by-step explanation:
2 (x+2) ^2-4=28
Add 4 to each side
2 (x+2) ^2-4+4=28+4
2 (x+2) ^2= 32
Divide by 2
2/2 (x+2) ^2=32/2
(x+2)^2 = 16
Take the square root of each side
sqrt((x+2)^2) =±sqrt( 16)
x+2 = ±4
Subtract 2 from each side
x+2-2 = -2±4
x = -2±4
x = -2+4 and x = -2-4
x = 2 x = -6
Answer:
The correct option is A.
Step-by-step explanation:
Consider the complete question is "The table shows the transportation method used by the employees in an office.
Transportation Number of employees
Car 18
Bus 6
Walk 6
what is the probability that the next two employees that join the office staff will take the bus? A.0.04, B.0.12, C.0.33, D.0.36.
Total number of employees = 18 + 6 + 6 = 30
The probability that the employees take the bus = 
The probability that the employees that join the office staff will take the bus is

Therefore, the correct option is A.
