Answer:
D. Open the compass so that the distance from the two points of the compass is wider than half the length of
.
Step-by-step explanation:
To construct a perpendicular for
, we must first take a compass & take the distance of its arms wider than half the length of
.
This is done in order to get two intersecting arcs in the top & bottom of
so that a perpendicular bisector can be drawn through it.
After two intersecting lines are drawn below & above
, draw a line joining these 2 points through their points of intersection. The point where it intersects
is the middle-most point of
& now a perpendicular bisector of
is constructed.

So 9x<18 can be factored out into
9(x)<9(2)
you can divide both sides by 9
x<2
so the solution is any number more than 2, but not 2
