Use effective reasoning to determine the composite number described.(1 point) I am a composite number. I am greater than 16, but less than 20. Two of my factors are a number and the number doubled. I am the number .
The composite number that satisfies the given conditions is 18.
To determine this, we need to find a number greater than 16 but less than 20 that has factors such that one of them is the number itself and the other is the number doubled.
Let's check the factors of the numbers in the given range:
For 17, the factors are 1 and 17. None of these factors satisfies the requirement.
For 18, the factors are 1, 2, 3, 6, 9, and 18. Among these factors, 6 and 12 are a number and the number doubled.
For 19, the factors are 1 and 19. None of these factors satisfies the requirement.
Therefore, the composite number described is 18.
