Answer 2

Answer:

Step-by-step explanation:

Algebraic expressions are useful because they represent the value of an expression for all of the values a variable can take on.

Sometimes in math, we describe an expression with a phrase. For example, the phrase

"two more than five"

can be written as the expression

5+25+25, plus, 2.

Similarly, when we describe an expression in words that includes a variable, we're describing an algebraic expression, an expression with a variable.
