If x = 3, what is the result of the expression (x+2)^2?

The correct answer is: 25

When x = 3, (x+2)^2 can be rewritten as (3+2)^2 or 5^2. This simplifies to 25, making D the correct answer. It is important to note that options A, B, and C are incorrect because they do not account for the exponent in the expression. Option A only adds 2 to the value of x, option B only adds 5 (the sum of 3 and 2), and option C only squares the value of x without adding 2. Therefore, they do not accurately represent the expression (x+2)^2. Option D is the only choice that accurately reflects the given expression.
