1. Multiple Choice 10 points Which expression, in factored form, is equivalent to \( f(x)=3(x-3)^{2}-12 \) ? \( \begin{array}{l}f(x)=3(x-1)(x-5) \\ f(x)=3 x^{2}-18 x+15 \\ f(x)=3(x-2)(x-3) \\ f(x)=3(x+1)(x+5)\end{array} \)

Elsa løper ei løype som er \( 1,75 \mathrm{~km} \) kortere enn den William loper, Tariq løper \( 15,95 \mathrm{~km} \), og det er 2,43 lenger enn William. Hvor langt løper Elsa og William?

в) \( x+15 \frac{3}{17}=20 \frac{14}{17} \) \( x= \) \( x= \) \( x= \)

7. \( 2 x^{2}+x-4=0 \) \( \begin{array}{ll}\text { a. }-\frac{1}{2} \pm \frac{\sqrt{33}}{4} & \text { c. }-\frac{1}{4} \pm \frac{\sqrt{33}}{4} \\ \text { b. }-4 \pm \frac{\sqrt{66}}{4} & \text { d. }-\frac{1}{2} \pm \frac{\sqrt{33}}{2}\end{array} \)

Solve the inequality. Express the solution set in set-builder notation and interval notation. Graph the solution set on a real number line. \[ 5(x-6)>4(x-6)+x \]
