9. You decide to run a marathon for a fundraiser. You donate $40 and then for every mile (m) you run, you also donate 3 dollars. If your total donation was $65, how many miles
did you run? Write an equation AND solve.

Two streets intersect at a 30- degree angle. at the intersection, the are four crosswalks formed that are the same length. what type of quadrilateral is formed by the crosswalks?

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

Quadrilateral abcd in the figure below represents a scaled-down model of a walkway around a historic site. quadrilateral efgh represents the actual walkway. abcd is similar to efgh. what is the total length, in feet of the actual walkway?
