Final answer:
To find two numbers that add to 12 and multiply to 36, consider the factors of 36 and find a pair that adds up to 12.
Step-by-step explanation:
To find two numbers that add to 12 and multiply to 36, we can consider the factors of 36. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. We need to find a pair of factors that add up to 12. The only pair that satisfies this condition is 4 and 9.
Therefore, the correct answer is option C) 4 and 9.
