Step1: Apply distributive property
The distributive property states that \(a(b + c)=ab+ac\). Here, \(a = - 4\), \(b=-9\) and \(c = 3x\). So we have \(-4\times(-9)+(-4)\times(3x)\).
Step2: Calculate each term
First term: \(-4\times(-9)=36\) (because multiplying two negative numbers gives a positive number). Second term: \(-4\times(3x)=-12x\) (multiplying a negative and a positive gives a negative number).
Step3: Combine the terms
Combining the two terms, we get \(36-12x\).
