Answer:
[tex]\frac{30x+30}{x+7}[/tex] is the simplified radical expression.
Step-by-step explanation:
For this one, we have fractions in the bottom of a fraction (denominator).
So, we would multiply by [tex]\frac{1}{x+1}[/tex].
[tex]\frac{5x+5}{\frac{1}{6}x+\frac{7}{6} }[/tex]
Then Multiply by 6.
[tex]\frac{30x+30}{x+7}[/tex] is the simplified radical expression.
