Answer: B - 11

Step-by-step explanation: Hello! How you can do this is by substituting A, B, C, and D for x.

D:

4(16)<45
64<45

64 is not less than 45, so this is false. D is not the answer.

C:
4(13.5)<45
54<45

54 is not less than 45, so this is false. C is not the answer.

A:
4(12)<45
48<45

48 is not less than 45, so this is false. A is not the answer.

B:
4(11)<45
44<45

44 is less than 45 so this is true.

The answer is B - 11.
