Answer
equivalent expressions
Work Step by Step
Using the Distributive Property, which is given by $a(b+c)=ab+ac,$ the expression , $2(4x+1),$ is equivalent to
\begin{array}{l}\require{cancel}
2(4x+1)
\\\\=
2(4x)+2(1)
\\\\=
8x+2
.\end{array}
Since this is the same as the second given expression, then the given are $\text{
equivalent expressions
.}$
