Final answer:
The constant term in the algebraic expression 3x + 11 is 11, which is the term that remains unchanged regardless of the variable x's value.
Step-by-step explanation:
The constant term in the expression 3x + 11 is 11. In algebraic expressions, the constant term is the term that does not contain any variables and remains fixed regardless of the value of any variables present in the expression.
In contrast, '3x' is a variable term because it consists of a variable 'x' and will change depending on the value of 'x'.
