C16.      4.7 / (9.4-3.5) = 4.7 / 5.9 = 0.79

C17      (2.3+1.8)^2 x 1.07 = (4.1)^2 x 1.07 = 16.81 x 1.07 = 17.98 

C14      3.8^2 - sqrt75 = 14.44 - 8.66 = 5.78 

                                                           = 5.8

C20      8.7x12.3 / (9.5-5.73)  = 107.01 / 3.77 = 28.38 

                                                                         = 28.4

C27      4.6+3.85 / (3.2^2-6.51) = 8.45 / (10.24 - 6.51) = 8.45 / 3.73 = 2.26

                                                                                                            = 2.3
