Answer 1

Solution:

Question:

Translate the following phrase to an expression: the product of a number and 2.

Let the number be

$=n$

The product of a number and 2.can be represented below as

$\begin{gathered} =n\times2 \\ =2n \end{gathered}$

Hence,

The expression is

$\Rightarrow2n$

When =18, we will have the evaluation be

$\begin{gathered} 2n \\ =2\times18 \\ =36 \end{gathered}$

Hence,

The final answer is

$2n;36$
