To rewrite the expression \(12x + 18\) in the format \(k(m + n)\), we need to factor out a common factor from both terms.
- First, identify the common factor of the coefficients 12 and 18. The greatest common factor (GCF) is 6.
- Next, factor out 6 from the expression:
\[ 12x + 18 = 6(2x + 3) \]
Therefore, you can fill in the blanks as follows:
\[ 12x + 18 = 6(2x + 3) \]
So, the completed equation is:
\[ 12x + 18 = 6(2x + 3) \]
Thus, the terms to fill in are:
- First blank: \(6\)
- Second blank: \(2x\)
- Third blank: \(3\)
