Answer:
The expression representing Noah’s new number is [tex](4x-3)^3.[/tex]
Step-by-step explanation:
Noah started with a number, x.
Four times the number x is 4x
The difference of four times the number and three is 4x - 3
The difference of four times the number and three cubed is [tex](4x-3)^3[/tex]
Thus, the expression representing Noah’s new number is [tex](4x-3)^3.[/tex]
