Question

Which description is paired with its correct expression?

Answer 1

The expression that is correctly paired is three more than the quotient of nine and a number cubed, decreased by 2 =$3+9/n^3-2$

Explanation

All the other expressions are not eligible to be paired with the description

consider the first description

The correct expression for this is $n^3/4 +8-2$

consider the second description

The correct expression for this is $6(5-n^2)$

consider the fourth description

The correct expression for this is $2(n^2-3)$

The only expression that matches its description is the third expression.
