x = 35 or B (this is your answer)
Step-by-step explanation:
I hope this helps :))
A prime number is such that it is divisible by only itself and one. ... Two is a prime because it is divisible by only two and one. All the other even numbers are not prime because they are all divisible by two. That leaves only the odd numbers.
