Question

first, lets try to isolate the variable, x. one of the x tern on the left. so, lets start by getting rid of the parenthe easier to work with. one way to do this is to distribute you can think of this as (3·x) + (3·6). rewrite 3(x + 6) = 3x + 18 3x + \square = 3x + 18

Explanation:

Step1: Recall the distributive property

The distributive property states that \(a(b + c)=ab + ac\). For \(3(x + 6)\), we distribute the 3 to both \(x\) and 6.

Step2: Calculate the constant term

We have \(3\times x=3x\) and \(3\times6 = 18\). So when we expand \(3(x + 6)\), it becomes \(3x+18\). Therefore, the missing term in \(3x+\square\) is 18.

Answer:

18
