Final answer:
To determine if the expression 8x + 8y + 8 is already simplified, we need to check if there are any like terms that can be combined. In this case, there are no like terms, so the expression is already simplified.
Step-by-step explanation:
To determine if the expression 8x + 8y + 8 is already simplified, we need to check if there are any like terms that can be combined. Like terms are terms that have the same variables raised to the same powers.
In this expression, all the terms are distinct and there are no like terms. Therefore, 8x + 8y + 8 cannot be simplified further.
