Identify the parts of the expression

The given algebraic expression is:
\[
3x + 2(x + 2) + 4
\]
It consists of three terms separated by addition operators:

• First term: \(3x\)
• Second term: \(2(x + 2)\)
• Last term: \(4\)

Analyze each specified component

• In the first term \(3x\), the number \(3\) is multiplied by the variable \(x\), making \(3\) a coefficient.
• In the second term \(2(x + 2)\), the expression \((x + 2)\) is multiplied by \(2\), making \((x + 2)\) a factor.
• In the last term \(4\), the number stands alone without any variables, making \(4\) a constant.
