Final answer:
The constant in the algebraic expression 14x+10 is 10, which is the term that does not contain the variable x and remains unchanged.
Step-by-step explanation:
The student has asked about identifying the constant in the algebraic expression 14x+10. In an algebraic expression, a constant is a term that does not contain any variables and remains unchanged. For the given expression, the constant is 10. This means that regardless of the value of x, the term 10 will always contribute the same amount to the value of the expression, differentiating it from the variable term 14x, which changes based on the value of x.
