2³+2²+2÷2²+2+1=2 prove that this relation is true for any natural numbers
UkoKoshka [18]

So, this question is basically asking us "If we had an x instead of a 2, would this be true?" We can try and see what we get:

\frac{x^3+x^2+x}{x^2+x+1}=x

So, if we want to show this we have to change the numerator or denominator in such a way that we can cancel some common factors. Notice that x^3+x^2+x=x(x^2+x+1)

If we replace the factored numerator with the original one, we get:

\frac{x(x^2+x+1)}{x^2+x+1}=x \implies \\ x=x

Since we have an equality, this relation is proved.

Please help explanation needed 22 points
emmasim [6.3K]
Alternate interior angles are:
(2x-70) = (x+30)
2x-x = 30+70
x = 100

the angle 5y is supplementary to the other angle.
5y + (100+30) = 180
5y + 130 = 180
5y = 180-130
5y = 50
y = 50/5
y = 10
