Final answer:
The given expression (x+3)/(3+x) simplifies to 1 based on the Commutative Property of Addition. This rule states that the order in assignment or addition does not affect the outcome, so in this scenario, (x+3) and (3+x) are identical.
Step-by-step explanation:
To simplify the expression (x+3)/(3+x), it is important to note that the order of addition does not change the results in mathematics. This principle, known as the Commutative Property of Addition, allows you to add numbers in any order and get the same result.
In this case, x + 3 is the same as 3 + x. Therefore, the expression (x+3)/(3+x) simplifies to 1 as the numerator and denominator represent the same numerical value for any given x.
