Answer: A. The number 23 is prime, but 36 is composite.
=====================================================
Explanation:
Let's go through the possible answer choices
- A) This is true because 23 only has the factors 1 and 23. So that's why 23 is prime. We can say 36 is composite since 2 is a factor, ie 36 = 2*18.
- B) This is false because 33 is not prime. Note how 33 = 3*11, showing that 3 is a factor of 33.
- C) Similar to B, the statement "21 is prime" is false. Note how 21 = 3*7.
- D) Like the other false statements, 27 is not prime because 27 = 3*9.

Step-by-step explanation:
f(x) × g(x)
= (x2 + 5x )× (3x2 -4x )
=3x4 + 15x3 - 4x3 -20x2
3x^4 + 11 x3 - 20x2
