Question

A sports company conducted a road test of a new model of a geared bike. The test rider cycled (3x - 2) miles on a flat road, (x2 - 5) miles uphill, and (2x + 7) miles downhill. Which simplified expression is equivalent to the total distance, in miles, for which the bike was tested?

Answer 1

Answer:

x² + 5x  miles

Step-by-step explanation:

Answer 2

From the way the question is worded, I think there's a list of choices
that's supposed to go along with it, and I'm sad and disappointed that
you decided not to share them.  But heck, ANYbody can pick the right
answer from a list of choices, but it takes a real Brainly to pick the right
answer from a list of no suggestions at all.

           (3x - 2) + (x² - 5) + (2x + 7) =

             3x - 2 + x² - 5 + 2x + 7  =

          (x²) + (3x + 2x) + (-2 - 5 + 7) =

                    x² + 5x  miles

            or   x (x + 5)  miles  (same thing)
