Question

Which is a correct statement about the description “two less than the quotient of a number cubed and sixteen, increased by eight” when n = 4?

The correct expression is . n cubed/16-2+8
The correct expression is . 2-n cubed/16+8
One of the steps to determining the value when n = 4 is 1-2+8.
One of the steps to determining the value when n = 4 is 2-1+8.
The value when n = 4 is 6.
The value when n = 4 is 7.
The value when n = 4 is 9.
The value when n = 4 is 10.

Answer 1

The correct expression is
`(n^(3))/(16)-2+8`

The value when
`n=4` is
`10`

Explanation:

Let

x------> a number

we know that

The algebraic expression of “two less than the quotient of a number cubed and sixteen, increased by eight” is equal to

`(n^(3))/(16)-2+8`

For
`n=4`

Substitute the value of n in the expression

`(4^(3))/(16)-2+8`

`4-2+8`

`10`

so

The value when
`n=4` is
`10`
