An object is thrown upward at a speed of 180 feet per second by a machine from a height of 20 feet off th ground. The height \( h \) of the object after \( t \) seconds can be found using the equation \( h=-16 t^{2}+180 t+20 \). (Round answers to two decimal places. Separate multiple answers with a comma.) When will the height be 394 feet? If there are two times, enter both times separated by a comma. Select an answer \( v \)

Solve the equation \( 9 x-8=2 x+6 \) algebraically. \( x=\square \)

ii) \( \quad x^{2}+x>2 \)

At a cafe, the total cost of a pizza includes the cost of a pizza and the cost of tra topping. The cost of a pizza with 4 toppings is \( \$ 10.00 \), and the cost of a pi th only 1 topping is \( \$ 8.50 \).

\[ \begin{array}{l}\text { Solve for the indicated variable. } \\ \qquad \frac{w-a}{n} ; \text { for } n \\ n=\square \text { (Simplify your answer.) }\end{array} \]
