ANSWER
[tex]35x+20[/tex]EXPLANATION
We want to simplify the expression given by using the distributive property:
[tex]5(7x+4)[/tex]To do this, we use the number outside the bracket to multiply each of the terms in the bracket.
That is:
[tex]\begin{gathered} (5\cdot7x)+(5\cdot4) \\ 35x+20 \end{gathered}[/tex]That is the answer.
