A ball is rolled uphill a distance of 4 meters before it slows, stops, and begins to roll back. The ball rolls downhill 12 meters before coming to rest against a tree. What is the ball's displacement?

8

Step-by-step explanation:

A ball is rolled uphill a distance of 4 meters

The ball rolls downhill 12 meters before coming to rest

Therefore the ball displacement can be calculated as follows

= 12-4

= 8

Hence the displacement is 8

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

i believe the answer is the polygon, heptagon.
