(Choice C) None of the above
C
None of the above

Answer 1

To simplify the expression \(-f-5(2f-3)\), distribute the -5 to each term inside the parentheses:

\(-f - 5(2f) + 5(3)\)

This simplifies to:

\(-f - 10f + 15\)

Combine like terms:

\(-11f + 15\)

So the expression \(-f-5(2f-3)\) is equivalent to \(-11f + 15\).

Therefore, the correct choices are (Choice B) \[-11f+15\].
