Step-by-step explanation:
Time taken by rayan to dig hole 
= 5 hours
Time taken by castel to dig hole 
= 6 hours
Now the time taken by both persons working together
Put all the values in above formula we get
T = 2.73 hours
Therefore the time taken by both boys to complete work = 2.73 hours
Answer:
Step-by-step explanation:
Solve for x:
x^2 + 4 x + 25 = 0 I ssume that's the notation.
Subtract 25 from both sides:
x^2 + 4 x = -25
Add 4 to both sides:
x^2 + 4 x + 4 = -21
Write the left hand side as a square:
(x + 2)^2 = -21
Take the square root of both sides:
x + 2 = i sqrt(21) or x + 2 = -i sqrt(21)
Subtract 2 from both sides:
x = i sqrt(21) - 2 or x + 2 = -i sqrt(21)
Subtract 2 from both sides:
Answer: x = i sqrt(21) - 2 or x = -i sqrt(21) - 2
