Answer:
C.
Step-by-step explanation:
A. 39 = 3 × 13; not prime
B. 33 = 3 × 11; not prime
C. 43 = 1 × 43; prime
D. 51 = 3 × 17; not prime
Answer: C.
(2x) + 11 < 44
x is multiplied by two because we are looking for twice of x. 11 is added to the 2x because we are looking for eleven more than the sum of twice of x. Since 2x + 11 is less than 44, we use the lesser than ( < ) symbol.
