Step-by-step explanation:
ΔABE and ΔACD are similar hence the ratios of corresponding sides are equal, that is
=
=
Using the first pair of ratios then
= 4 =
, hence
4ED = 26 ( divide both sides by 4 )
ED = 6.5 cm

Similarly
= 4, hence
BE = 4 × 18 = 72 cm
100 as a product of its prime factors:
Answer:
see the explanation
Step-by-step explanation:
step 1
Find the scale factor of the dilation
Divide the x-coordinate or the y-coordinate of the image by the the x-coordinate or the y-coordinate of the pre-image
so
or
step 2
Multiply the coordinates of point B by the scale factor to obtain the image B'
B'(1.5*1,1.5*4)
B'(1.5,6)
