Question

D = { x : x € N, x is a composite number, 10 ‹ x ‹ 18 }​

Answer 1

Answer:

D = {12,14,15,16}

Explanation:

A composite number is a positive integer that can be formed by multiplying two smaller positive integers.  It has at least one divisor other than 1 and itself.

For example, the integer 14 is a composite number because it is the product of the two smaller integers 2 × 7.
