Final answer:
To simplify the expression 2h + 6h² + 5h, combine like terms by adding the coefficients of the same variable. The simplified expression is 7h + 6h².
Step-by-step explanation:
To simplify the expression 2h + 6h² + 5h, we can combine like terms. Like terms have the same variable raised to the same power. In this case, the like terms are 2h and 5h, as they both have the variable h raised to the first power.
To simplify, we add the coefficients, which are the numbers in front of the variable h. 2h + 5h equals 7h. So, the simplified expression is 7h + 6h².
