9.

Since w(-7) = 9 and x equals -7, than you get the same solution.

Solve the inequality.<br> 3x+6<3(x-7)

<h3> $\boxed{\large\displaystyle\text{$\begin{gathered}\sf \bf{3x+6 < 3(x-7) } \end{gathered}$} }$ </h3>

Simplify both sides of the inequality.

$\boxed{\large\displaystyle\text{$\begin{gathered}\sf \bf{3x+6 < 3x-21 } \end{gathered}$} }$

Subtract 3x from both sides.

<h3> $\boxed{\large\displaystyle\text{$\begin{gathered}\sf \bf{3x+6-3x < 3x-21-3x } \end{gathered}$} }$ </h3><h3> $\boxed{\large\displaystyle\text{$\begin{gathered}\sf \bf{6 < -21 } \end{gathered}$} }$ </h3>

Subtract 6 from both sides.

<h3> $\boxed{\large\displaystyle\text{$\begin{gathered}\sf \bf{6-6 < -21-6 } \end{gathered}$} }$ </h3>

$\boxed{\large\displaystyle\text{$\begin{gathered}\sf \bf{0 < -27} \end{gathered}$} }$

If you work out the constants it says:

25+x²=100

Which simplifies to x=√75 or x=-√75
