Like terms are terms whose variables and exponents are the same.
8 is a constant term, which means it is a number without a variable.
So, among the given choices, we chose those terms that are constants to be alike with 8.
X - a variable
15 - a constant
32x - a term with constant and variable
1 - a constant
14y - a term with constant and variable
12 - constant
Therefore, choices B, D and F are like terms with 8.
The answer: B, D and F
