To factor the expression \(-42k - 54\), we first look for the greatest common factor (GCF) of the coefficients \(-42\) and \(-54\).

The GCF of \(-42\) and \(-54\) is \(-6\).

Now, we can factor out \(-6\) from the expression:

\[ -42k - 54 = -6(7k + 9) \]

So, the equivalent factorization of the expression \(-42k - 54\) is:

\(-6(7k + 9)\)

None of the provided options are correct based on the factorization steps. It seems "−6(7k+9)" was not included in your responses. Please double-check the options.

The closest correct option to the answer we derived correct is:

−6(7k + 9)
