If by d2 you mean d squared then it is non linear
It is linear in c and non-linear in d. If both c and d are variables, then it is non-linear.
36 inches = 3 feet
36+27=63
27 + 9 = 36
The answer is: 144+36 + 180
It is linear in c and non-linear in d. If both c and d are variables, then it is non-linear.
36 inches = 3 feet

36 inches plus what?
36+27=63
27 + 9 = 36
21 + 15 = 36
36 + 12 = 48
