Which factorization is equivalent to this expression?

-42k-54

(-2)(21k+27)

To find the equivalent factorization of the expression -42k-54, we need to factor out the greatest common factor (GCF) from the given terms.

Step 1: Determine the GCF of -42k and -54.
The GCF of -42 and -54 is 6, since both numbers can be divided evenly by 6.

Step 2: Factor out the GCF from both terms.
-42k can be factored as -6 * 7 * k, and -54 can be factored as -6 * 9.

So, the factorization of -42k-54, factoring out the GCF, is:
-6(7k + 9)

To factorize the expression -42k - 54, we can find the greatest common factor (GCF) of the two terms.

The GCF of -42k and -54 is 6.

So, we can rewrite the expression as:

6(-7k - 9)

The factored form of the expression -42k - 54 is 6(-7k - 9).
