Answer: Option C.

Explanation:

x = 10.8

A. = 4,320 ÷ x

= 4,320/10.8

Option A is incorrect.

B. = 288/x + 16

= 288/10.8 + 16

= 42.7

Option B is incorrect

C. = (x² ÷ 18) + 33.52

= 40

Option C is correct

D. = (1,752 ÷ x) – 162/29

= (1,752 ÷ 10.8) – 162/29

= 156.6

Option D is incorrect

E. = x/12 + 36

= 10.8/12 + 36
