C2/d at c = 6, d =3
really confused on this one
can you evaluate the algebraic expressions for the given values of each variable?

If the C2 is referring to C^2 (c squared), then 

C^2 = 6^2 = 6*6 = 36
Note how I replaced the "C" with 6, because C = 6
Squaring a number is the same as multiplying it by itself. 

Once you know the value of C^2, you divide it over the value for d, which is 3

So,
(C^2)/d = (36)/3 = 12

The final answer is 12

Idon’t understand what you’re asking..
