waht's the question?

Answer 2

It's the second attachment

Answer 3

i don't understand the question ! sorry
call another hero

Answer 4

Lol thanks for trying

Answer 5

after dilatid by a scale factor of 3
B(12,13) ------> B' = (36,39)
C(8,10) ------> C' = (24,30)

so, the length of B'C' =
d = sqrt( (x2-x1)^2 + (y2-y1)^2 )
d = sqrt( (39-30)^2 + (36-24)^2 )
d = ...
just simplfy that, get your answer ...

Answer 6

Still confused how would I simplify it?

Answer 7

whats 39-30 ? then square it
whats 36-24 ? then square it

add up both, then take the quareroot

Answer 8

Alright thanks

Answer 9

welcome

Answer 10

>>No I'm not really sure what I'm doing wrong 39-30 would be 9 the square root would be 3 then 36-24 is 12 and the square root is 3.46410161514 If I where to add them up and get the square it it wouldn't be 15. What did you do to get 15.
