In triangle ABC, points and Eare the midpoints of AB and AC respectively. What are the slope and length of DE, if the slope and length of BC
are 0.5 and 3.2 units, respectively?
ОА slope = -2, length = 3.2 units
OB. slope = 0.25, length = 3.2 units
Oc slope -0.5, length = 1.6 units
OD
slope = -2, length = 1.6 units
ОЕ slope = 0.25, length = 1.6 units

sry but any answer choices

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
