Using diagonals from a common vertex, how many triangles could be formed from the polygon pictured below?

Which describes the difference between the graph of f(x)=x^2 and g(x)=-(x^2-2)

The numbers on a football field indicate 10 yard increments. you walk around the perimeter of a football field between the pylons. you walk a distance of 30623 yards. find the area and perimeter of the indicated regions. write your answers as mixed numbers, if necessary. a. one end zone: perimeter: yd area: yd2 b. the playing field (not including end zones): perimeter: yd area: yd2 c. the playing field (including end zones): perimeter: yd area: yd2

Rationalize the denominator- 12x/√x-10
