Answer:
four less than the quotient of a number cubed and seven, increased by three 
five times the difference of a number squared and six

nine more than the quotient of six and a number cubed, decreased by four

twice the difference of nine and a number squared

Step-by-step explanation:
Let n the number of interest we have this:
four less than the quotient of a number cubed and seven, increased by three 
five times the difference of a number squared and six

nine more than the quotient of six and a number cubed, decreased by four

twice the difference of nine and a number squared:
