The center of a sphere is
[1] a line segment from the center point to the surface of the sphere.
[2] a fixed point equidistant from all points on the surface of the sphere.
[3] a three-dimensional circle in which all points are equidistant from a fixed point.
the same as the base of the sphere.

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.

Identify the expression equivalent to 4(x + x + 7) − 2x + 8 − 4 by substituting x = 1 and x = 2.
