Using the graph shown, answer this question: What is the scale factor used to dilate the figure?

5. AriPotta

count the length of the sides for each rectangle

Okay. Let me count.

just one side?

8. AriPotta

yea, just make sure they're corresponding. like, the long side of the big one and long side of the small one

Okay.

10. Kitt020912

let ari take over, I got nothing lol.

Will it be by 2's or ones?

12. AriPotta

it's by 1's

Okie, Kitt. I like ur picture too

14. AriPotta

always assume by 1's if it's not labeled

Okie, Ari

Can it be CB an CB'?

(' Means the dilation or second version of a figure.)

18. AriPotta

yea count them. then put cb/cb' and figure out the scale factor

Ok.

$\frac{ CB }{ CB' } = \frac{ 9 }{ 2 }$

?

So is the scale factor 4.5?

(I divided 9/2)

24. AriPotta

9/3

O

Okiee.

27. AriPotta

which would give us scale factor of 3

Ohhh. Okay. So answer = 3?

29. AriPotta

wait no. put cb'/cb which would be 1/3

30. AriPotta

OH. OK. WHY WAS THE FIRST ONE WRONG?

32. AriPotta

because if we said the scale factor was 3, then cb' would be 3x the size of cb. but it's not. it's 1/3 the size.

Oh. Okay. Thanks!

[since its smaller it can't b 3 times the size right?]

lol yes
