Answer:
Step-by-step explanation:
We can write our unknown number like x
four less than the quotient of a number cubed and seven, increased by three
[tex]4-\frac{x^3}{7}+3[/tex]
five times the difference of a number squared and six
[tex]5(x^2-6)[/tex]
nine more than the quotient of six and a number cubed, decreased by four
[tex]9+\frac{6}{x^3}-4[/tex]
twice the difference of nine and a number squared
[tex]2n^2-9[/tex]
