Question

Select all expressions that are equivalent to 3x + 5+ 4(x + 2) +2.7x + 97 + 7x + 85 + 11x + 24x + 3x + 15

Answer 1

Given the expression

$3x\text{ + 5 + 4(x + 2) + 2}$

We can simplify the expression into :

$\begin{gathered} 3x\text{ + 5 + 4x + 8 + 2} \\ \end{gathered}$

This expression can be simplified further into:

$\begin{gathered} a.7\text{ + 7x + 8 } \\ b\text{. 4x + 3x + 15} \end{gathered}$

Hence, the correct options are (7 + 7x + 8) and (4x + 3x + 15)
