@AllTehMaffs I need u

OpenStudy (anonymous):

I can't open .docx 's :/ What is it?

OpenStudy (anonymous):

can you tale a screen shot of the page?

OpenStudy (anonymous):

it is a screenshot u just have to open it and itll open on ur computer as word

OpenStudy (anonymous):

therein lles the rub.

OpenStudy (anonymous):

huh

OpenStudy (anonymous):

that's the problem. Word. I sec...

OpenStudy (anonymous):

not workin' for me :/

OpenStudy (anonymous):

oh it isn't wat does it say

OpenStudy (anonymous):

got it. if the pictures are similar, you can just set up a proportion. What do you think the answer is?

OpenStudy (anonymous):

umm...

OpenStudy (anonymous):

Im not sure really

OpenStudy (anonymous):

If the proportions of each side have to be the same, then |dw:1382800854704:dw| \[\frac{B}{A} = \frac{D}{C} \]

OpenStudy (anonymous):

mhm..

OpenStudy (anonymous):

The little drawing is 5x2 the big drawing is 10.5x?

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

do you see where I'm going with this?

OpenStudy (anonymous):

yes I do:)

OpenStudy (anonymous):

u there

OpenStudy (anonymous):

are you there still

OpenStudy (anonymous):

hi, yeah

OpenStudy (anonymous):

ok kool:)

OpenStudy (anonymous):

man I just need the answer:(

OpenStudy (anonymous):

well I'm not given it to ya :) yuuz ya brainz! A/B is the relationship between the short side of the original picture to the long side of the original picture. D/C is the relationship between the short side of enlarged picture to the large side of the enlarged picture. \[ \frac{A}{B} = \frac{C}{D} \\ \ \\ \frac{A}{B} D = C\] You're looking for C

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

this problem is hard

OpenStudy (anonymous):

It takes a few steps, yep :)

OpenStudy (anonymous):

I know

OpenStudy (anonymous):

but I don't get it

OpenStudy (anonymous):

So when I say "A/B is the relationship between the short side, A, and the long side, B," I mean \[ \frac{A}{B} = \frac{2}{5} \] The length of the short side divided by the length of the long side. That gives you a number (.4 in this case). For the enlarged drawing to have the same proportions as the original drawing, "C\D - the relationship between C, the short side of the enlarged drawing, and D, the long side of the enlarged drawing," ha to equal that same number. That's what similarity of rectangles is defined as :) Does that make sense?|dw:1382802797498:dw|
