Similar triangles so AC:BC=AE:DE
15+6=21 = AE
15:12.5=21:?
to get from 15 to 12.5 you divide by 15 and times by 12.5 so do this the to the other side
21/15=1.4
1.4 x 12.5=17.5
So DE=17.5

Answer:
it means you just gotta multiply it fam its 888
Step-by-step explanation:
First, figure out its slope. that is (4-2)/(2-1)=2
then, write its point-slope form:
y-(-3)=2(x-2)
