Answer 2

Answer:

$\boxed {\tt 21n}$

Step-by-step explanation:

We want to write the product of a number and 21 as an algebraic expression.  Let's define "a number" as the variable n.

We know that "product" means multiplication. The product of a number, n, and 21 is equal to multiplying n and 21.

$n*21$

21 and n can be flipped due to the commutative property of multiplication.

$21*n$

$21n$

The product of a number and 21 is 21n.
