Which description is paired with its correct expression? Four less than the quotient of a number cubed and seven 4 - n3/7 + 3

Five times the difference of a number squared and six 5(6 - n2)

Nine more than the quotient of six and a number cubed decreased by 4 9 + n3/6 - 4

Twice the difference of nine and a number squared 2(9 - n2)

I think it’s D
