D the slope of the line is a zero slope
<span>The diagonals of a rectangle have equal lengths. Since AC has a length of 28,
and AC is a diagonal, the other diagonal BD also has a length of 28.
The diagonals of a rectangle also bisect each other. So diagonal BD is
bisected by the other diagonal AC at point E. And since diagonal BD has
a length of 28 then BE and ED both have a length which is of 28,
or 14 each.
Answer: ED has a length of 14.</span>
You can conclude that AE = DE because the triangles are about equal
Yes, because the sample is random. If she had chosen the participants in any way other than randomly, it would not be representative of her entire school.
