Given the expression
[tex]3x\text{ + 5 + 4(x + 2) + 2}[/tex]We can simplify the expression into :
[tex]\begin{gathered} 3x\text{ + 5 + 4x + 8 + 2} \\ \end{gathered}[/tex]This expression can be simplified further into:
[tex]\begin{gathered} a.7\text{ + 7x + 8 } \\ b\text{. 4x + 3x + 15} \end{gathered}[/tex]Hence, the correct options are (7 + 7x + 8) and (4x + 3x + 15)
