The general name is a "constant".
It could
In the expression (7 + 2x), the constant is (7). A constant is a term that does not change and does not contain any variables, while (2x) is a term that depends on the variable (x). Therefore, (7) remains the same regardless of the value of (x).
A mathematical phrase that can contain ordinary numbers, variables, and operators is called an "algebraic expression." It can include constants (like 3 or 5), variables (like (x) or (y)), and operators (such as +, -, *, or /). For example, (2x + 5 - y) is an algebraic expression that combines these elements.
In the expression (9x - 19), the constant is (-19). Constants are the terms that do not contain any variables, and in this case, (-19) is the only term that remains fixed regardless of the value of (x).

A term must contain a variable, for it to be relevant.

What are the choices?
In the expression (7 + 2x), the constant is (7). A constant is a term that does not change and does not contain any variables, while (2x) is a term that depends on the variable (x). Therefore, (7) remains the same regardless of the value of (x).
An expression is made up of numbers and variables joined by mathematical operations.
A polynomial is a type of algebraic expression. They differ in the number of terms that contain variables. An algebraic expression has at least 1 variable, while a polynomial has multiple terms with variables in it.
Maybe the word you're looking for is: term.
An expression consists of numbers and variables that may be linked by mathematical functions. Other than in a conditional phrase, an expression may not contain an equality or inequality.
They are "like" terms.
In the expression (9x - 19), the constant is (-19). Constants are the terms that do not contain any variables, and in this case, (-19) is the only term that remains fixed regardless of the value of (x).
