Question

Noah started with a number, x. He took the difference of four times the number and three and cubed the result. Write the expression representing Noah’s new number.

Answer 1

Answer:

The expression representing Noah’s new number is $(4x-3)^3.$

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 $(4x-3)^3$

Thus, the expression representing Noah’s new number is $(4x-3)^3.$
