Trying to factor as a Difference of Cubes
2.1 Factoring: 8x2y3-5
Theory : A difference of two perfect cubes, a3 - b3 can be factored into
(a-b) • (a2 +ab +b2)
Proof : (a-b)•(a2+ab+b2) =
a3+a2b+ab2-ba2-b2a-b3 =
a3+(a2b-ba2)+(ab2-b2a)-b3 =
a3+0+0+b3 =
a3+b3
Check : 8 is the cube of 2
Check : 5 is not a cube !!
Ruling : Binomial can not be factored as the difference of two perfect cubes
Final result :
8x2y3 - 5

Answer:
la diferencia es 12.109
Step-by-step explanation:
4807 - (-7302) es negativo ya que la fosa está en la profundidad.
4807 + 7302 (se multiplican los signos en la primera)
=12.109
2 standard deviations contain 95% confidence. So thus you would have 4hrs in either direction. So the interval at which we could feel 95% confident is between 11-19hrs.
Answer:
75%
Step-by-step explanation:
now we can see that our fraction is 75/100 which means that 42/56 as a percentage is 75%
