Ok so solve each
A. c+14<24
c<10
false since 10 is included in the solution set (and > means not including as well)
B. C+18<u>></u>24
subtract 18
C<u>></u>6
false since 5 is in the solution set (and 5<6)
C. C+18>24
subtract 18
C>6
false again since 5 is included
D. C+14<u><</u>24
subtract 14
C<u><</u>10
treu since <u><</u> means c is less than or equal to 10
answer is D
10 to the 4th power is the answer.
