To factor the expression \(48y + 36z\) using the greatest common factor (GCF), we first need to determine the GCF of the coefficients 48 and 36.
- The factors of 48 are \(1, 2, 3, 4, 6, 8, 12, 16, 24, 48\).
- The factors of 36 are \(1, 2, 3, 4, 6, 9, 12, 18, 36\).
The greatest common factor of 48 and 36 is \(12\).
Next, we can factor out \(12\) from the expression:
\[ 48y + 36z = 12(4y + 3z) \]
Thus, the correct factored form of the expression is:
12(4y + 3z)
So, the correct response from the options given is:
12(4y + 3z).
