In can be less mental effort if the equation is multiplied by -1 first.
.. x^2 -10x +8 = 0
.. x^2 -10x +25 +8 -25 = 0
.. (x -5)^2 = 17
.. x -5 = ±√17
.. x = 5 ±√17
The values of x that satisfy the given equation are
.. x = 5 -√17 ≈ 0.877
.. x = 5 +√17 ≈ 9.123
Answer:
2.7 x 5.2 = 14.04
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given
Rate of flow = 1.6gallons per minute
Amount of gallon bucket = 4gallons
Required
Time taken to fill 4gallon bucket
Rate = Amount of gallon/Time
Time = Amount of gallon/Rate
Time = 4/1.6
Time = 2.5
Hence it will make 2.5minutes to fill 4gallon bucket
