Which of the following are algebraic expressions?
2(x + 3) + 4 is an algebraic expression.
An algebraic expression is a mathematical phrase that can include numbers, variables, and operation symbols, but does not include an equality or inequality sign. The expression 2(x + 3) + 4 satisfies this definition as it combines numbers and variables using arithmetic operations.
This choice is an algebraic expression because it includes numbers and a variable (x) combined through addition and multiplication operations. It does not have an equality or inequality sign, fitting the definition of an algebraic expression perfectly.
This option is not an algebraic expression; instead, it is an equation. An equation states that two expressions are equal to each other, which is indicated by the equal sign (=). In contrast, algebraic expressions do not express equality and only represent a value.
Similar to option B, this is also an equation due to the presence of the equality sign (=). While 3y + 7 is an algebraic expression, the entire statement cannot be classified as such because it asserts that x is equal to this expression rather than simply representing a value.
This choice is an algebraic expression, as it consists of constants and variables combined through addition and subtraction without any equality or inequality sign. However, since the correct answer to the question specifically asks for one correct expression, it is not the answer being sought here.
Algebraic expressions are defined by their lack of equality or inequality signs, allowing them to represent values through combinations of numbers and variables. Among the given options, 2(x + 3) + 4 exemplifies this definition, while the other choices either present equations or also qualify as algebraic expressions but do not fulfill the question's requirement for the specific correct answer.
