Acircular roller derby ring has a diameter of 95 feet. if a roller derby player skates five laps around the rink, how far has she traveled?

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)

Need plz been trying to do it for a long time and still haven’t succeeded

Factor the following expression completely 6x^11-24x^7
