A gardener has 440 feet of fencing to fence in a rectangular garden. One side of the garden is bordered by a river and so it does not need any fencing. What dimensions would guarantee that the garden has the greatest possible area? Round all answers to the nearest whole number. a. Shorter side: b. Longer side: c. Greatest possible area:

Question simplify: \( \sqrt[6]{x^{18}} \)

Question Simplify: \( \sqrt{9+16} \) (Enter \( \varnothing \) if your answer is not a real number.)

Question Simplify: \( \sqrt[3]{-125} \) (Enter \( \varnothing \) if your answer is not a real number.)

Question Estimate \( \sqrt{35} \) to two decimal places.

\( 1 \leftarrow \quad \begin{array}{l}\text { Write the first four terms of the recursive sequence. } \\ a_{1}=6, a_{n}=5-a_{n-1} \text { for } n \geq 2\end{array} \) \( a_{1}=\square \) (Type an integer or a simplified fraction.)
