The distance between them is 8 feet. Don't know if it needs to be negative.
The parabola goes down(makes a sad face) because it is negative. The answer is 0,0
Solve for s.
p=4s
Flip the equation.
4s=p
Divide both sides by 4.
4s/4=p/4
s=1/4p
1/6x = 2.....multiply both sides by the reciprocal 6/1
(6/1)(1/6)x = 2(6/1)
1x or just x = 12
