It takes Kendrick 20 minutes to travel 5 miles to school on his bicycle. Which correctly shows the relationship between the distance Kendrick travels and time? A Kendrick travels 15 miles per minute. B Kendrick travels 4 miles per minute. C. Kendrick travels 0.25 mile per minute. D Kendrick travels 1.25 miles per minute.

G. \( \left(\frac{2}{3}\right)^{3 x-2} \cdot\left(\frac{4}{9}\right)^{2 x+1} \leq\left(\frac{8}{27}\right)^{x-3} \) H. \( 2^{x-1}+2^{x}+2^{x+1}-2^{x+2}+2^{x+3}>240 \) I. \( 3^{x+5}-3^{x+4}+3^{x+3}-3^{x+2}<540 \) J. \( 4^{x}-6 \cdot 2^{x}+8<0 \) K. \( 3^{2 x}-3^{x+1}>3^{x}-3 \) L. \( 3^{x}\left(3^{x}-1\right) \geq 1-3^{-x} \)

Solving using the Quadratic Formula. \( \begin{array}{l}x^{2}+3 x-3=0 \\ x=\frac{3 \pm 2 \sqrt{5}}{2} \\ x=\frac{-3 \pm \sqrt{21}}{2} \\ x=\frac{3 \pm \sqrt{21}}{2} \\ x=\frac{-3 \pm i}{2}\end{array} \)
