Answer: The correct options are :
(B) [tex]-3.7,[/tex]
(C) [tex]\dfrac{1}{3},[/tex]
(F) [tex]12.[/tex]
Step-by-step explanation: We are given to select all the constants in the following expression :
[tex]E=12+x-3.7-8y+\dfrac{1}{3}~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We know that
in an algebraic expression, the constants are those terms which are not multiplied to some unknown variables.
In the given expression (i), there are two unknown variables x and y.
So, the terms which are not multiplied by x or y are the constants in the expression.
Therefore, the required constants are
[tex]12,~~-3.7,~~\dfrac{1}{3}.[/tex]
Thus, (B), (C) and (F) are the correct options.
