Kayla squared a number x and added this result to -6.5. This gave her an answer of 42.5. What is the equation and one of the solutions to this equation?
A. X2 + (-6.5) = 42.5; 2 = 7
B. X2? + (-6.5) = 42.5; 2 = 6
C.2x+ (-6.5) = 42.5; x = 24.5
D.2x+ (-6.5) = 42.5; I = 18

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
