What is/are the x -intercepts of the graph y=−x6−6x5+50x3+45x2−108x−108 y = − x 6 − 6 x 5 + 50 x 3 + 45 x 2 − 108 x − 108 ?

If given an equation of a line such as -1/2x+6 how would you create an equation of a line parallel and perpendicula to this line that goes through another point such as (4,10)

Does the point (1, sqrt 7) lie on circle shown.

The width of a rectangle is 20 units. can the perimeter p of the rectangle be 64 units when its length x is 11 units? no, because p = 2x + 2(20) no, because p ≠ 2x + 2(20) yes, because p ≠ 2x + 2(20) yes, because p = 2x + 2(20)
