Select all the expressions that have a value of 40 when x = 10.8.

A 4,320 ÷ x
B 288/x + 16
C (x² ÷ 18) + 33.52
D (1,752 ÷ x) – 162/29
F x/12 + 36

Answer 1

The answer is C.

Explanation:

I solved each expression and only C. had 40 as the answer.

A. 4,320 / 10.8 = 400

B. 288/10.8 + 16 = 42.6666667

C. (10.8^2 / 18) + 33.52 = 40

D. (1,752 / 10.8) - 162/29 = 156.636015326

F. 10.8/12 + 36 = 36.0666666667

So, the answer is C.

Hope this helps! :)
