OpenStudy (anonymous):

PB has endpoints at -2 and 12. What is the coordinate of it's midpoint?

OpenStudy (anonymous):

The midpoint of CD is E(-1,0). One endpoint is C(5,2). What are the coordinates of the other endpoint?

OpenStudy (sleepyjess):

@krys-taylor , Welcome to OpenStudy! Please don't give direct answers.

OpenStudy (anonymous):

yea ok

OpenStudy (sleepyjess):

@AquaStone316 , for the first one, we need to find the area of the large rectangle first, http://prntscr.com/6071nv

OpenStudy (anonymous):

The first question is already done, I just need the answers to the other 2 questions.

OpenStudy (sleepyjess):

The answer that @krys-taylor gave is incorrect though.

OpenStudy (anonymous):

thats cause your a mathlete lol

OpenStudy (sleepyjess):

What is?

OpenStudy (anonymous):

How is it wrong?

OpenStudy (sleepyjess):

That is what I am trying to explain.

OpenStudy (anonymous):

so explain

OpenStudy (anonymous):

Ok then explain please because in my offense I'm very dumb when it comes to Geometry.

OpenStudy (sleepyjess):

What is the area of the large rectangle?

OpenStudy (sleepyjess):

The one in red here: http://prntscr.com/6071nv

OpenStudy (sleepyjess):

Don't say that you are dumb, that is why I am helping you, so you are not "dumb".

OpenStudy (anonymous):

25

OpenStudy (sleepyjess):

Why 25? How did you get to that?

OpenStudy (anonymous):

9(on top) + 2 + 4(the bottom) + 5 + 5(sides) = 25

OpenStudy (sleepyjess):

Remember, area is base times height.

OpenStudy (sleepyjess):

9 is the base, 5 is the height

OpenStudy (anonymous):

So 45.

OpenStudy (sleepyjess):

Yep, now, what is this length? http://prntscr.com/6075kz

OpenStudy (anonymous):

3

OpenStudy (sleepyjess):

Yes, now we need to subtract the area of that small square from the area of the large rectangle. What is the area of the small square?

OpenStudy (anonymous):

3

OpenStudy (sleepyjess):

That is the length and height, so what is 3*3?

OpenStudy (anonymous):

9

OpenStudy (sleepyjess):

Yep, now what is 45-9?

OpenStudy (anonymous):

34

OpenStudy (sleepyjess):

That is 45-11

OpenStudy (anonymous):

36, sorry that was a typo.

OpenStudy (sleepyjess):

Yep :) so 36 is your answer

OpenStudy (anonymous):

Ok thanks, now can you please answer my other 2 questions?
