Praxis 5003 Practice Question
Which of the following are algebraic expressions? Select ALL that apply.
Correct Answer: A,D
Rationale: Algebraic expressions consist of numbers, variables, and operations, but do not include equations or inequalities.
Option A, \(2 \cdot (x + 3) + 4\), is an algebraic expression as it combines constants and a variable through multiplication and addition.
Option B, \(4 = x^2\), is an equation, not an expression, as it sets two values equal to each other.
Option C, \(x = 3y + 7\), is also an equation because it asserts a relationship between \(x\) and \(y\).
Option D, \(4y^2 + 2y - 3\), qualifies as an algebraic expression since it consists of terms involving variables and constants combined through addition and multiplication.
