Tor F? The following expression
is Prime (cannot be factored) 8x
+ 15
O True
False

Answer 1

FALSE

Explanation:

Hmm... For this type of question, lets plug some numbers in

8(1) + 15 = 8+15 = 23 which is a prime

8(2) + 15 = 16 + 15 = 31 which is also a prime

8(3) + 15 = 24 + 15 = 39. but wait... 39 isn't a prime!

so that means this equation does not get prime numbers

Answer 2

It’s FALSE. As soon as x=10, the expression is not prime anymore and can be factored to 5 and 19.
