Answer:
Composite
Step-by-step explanation:
To know if the number is a prime or composite, you must first know the definitions of both words.
Prime: Prime means that the number only has factors of 1 and itself. An example can be 13, in which it only has factors of 1 and 13.
(1 * 13 = 13).
Composite: Composite means that the number has more factors then just 1 and itself. An example can be 20, in which the factors are 1, 2, 4, 5, 10, 20.
(1 * 20 = 20).
(2 * 10 = 20).
(4 * 5 = 20).
Now, the question asks 85. 85 is a composite number, for it has more than just 1 & 85 as factors. The factors will be listed below:
(1 * 85 = 85)
(5 * 17 = 85)
1, 5, 17, 85 are your factors.
