Final answer:
In algebra, the terms of the expression 5h+9 are 5h and 9, where 5h is a variable term and 9 is a constant.
Step-by-step explanation:
The expression 5h+9 consists of two terms. In the context of algebra, a term is a single mathematical expression that may consist of numbers, variables (letters that represent numbers), or the product of numbers and variables. In this expression, 5h is the first term and represents five times whatever number 'h' stands for. The second term is 9, which is just a constant or a number.
