- 3smh - 5stg
- 3t - 2b + h - 23
- 4mo - od
- 6al
Analyzing the Choices
A. 24 + 8 - 7
Is it an algebraic expression? Why or why not? No, because it lacks variables and algebraic operations that make it only an expression.
B. 36 + 1 / 9 = 4
Is it an algebraic expression? Why or why not? No, it has two expressions that are indicated by an equal sign to say they are equal that makes it an equation.
C. 12c + 15 = 38
Is it an algebraic expression? Why or why not? No, it has two expressions, variables, and algebraic operations that are indicated by an equal sign to say they are equal that makes it an algebraic equation.
D. 8y - 45m
Is it an algebraic expression? Why or why not? Yes, it has integer constants, variables, and algebraic operations that make it an algebraic expression.
Therefore, 8y - 45m (Letter D) is an algebraic expression.
