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

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

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.`
