Question

Which property of real numbers is shown below?

Answer 1

a

Explanation:

Answer 2

Answer: (A)
`(x^(2)+14x)/(9x^(2))`

Explanation:

`(2x)/(x^(2))` +
`(x-4)/(9x)`

=
`(2x)/(x^(2))*((9)/(9))` +
`(x-4)/(9x)*((x)/(x))`

=
`(18x)/(9x^(2))` +
`(x^(2)-4x)/(9x^(2))`

=
`(18x+x^(2)-4x)/(9x^(2))`

=
`(x^(2)+14x)/(9x^(2))`

NOTE: This was an odd question because you should reduce the first fraction
`(2x)/(x^(2))` to
`(2)/(x)` before finding the common denominator. The simplified answer is:
`(x+14)/(9x)`
