What is the length of a side of this regular polygon if its perimeter is 72 inches?

All you would have to do in this problem is divide. What would you divide? Well, that would be the total perimeter by the number of sides. Can you try to figure it out yourself from here?

All you need to do is divide 72 by 8 and you would get 9. it is long division

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0
