<span>3d - 6 = 5 --> add 6 to each side
3d = 11 --> divide by three on each side
</span>D = 3.66666666
I’m pretty sure the answer is 7/18
we are given

Firstly, we will factor numerators and denominators

we can see that
n^2 -6 is factor on both numerator and denominator
so, it will get cancelled
and n^2 -6 can not be equal to 0
so, one of restriction is


we can simplify it

we know that denominator can not be zero


so, option-B.......Answer
