huh. that's interesting.

Becquerel · July 23, 2014, 10:38:52 PM

radius is 3

Bosnik · July 23, 2014, 10:42:29 PM

wtf that's not even difficult, are you in pre-algebra? the radius is 3

hillkill · July 23, 2014, 10:43:41 PM

i was in pre-algebra and we didnt even learn this lol

Bosnik · July 23, 2014, 10:45:59 PM

i definitely learned that in pre-algebra or very early algebra 1

Becquerel · July 23, 2014, 10:48:11 PM

I cant remember anything out of Algebra 1. School starts up in about 3-4 weeks for me so I should brush up on my math skills.

I don't remember finding the radius of a circle thru the values of x and y.

Wait is this some forgeted up way of FOIL.
Oh yeah factoring.

I think. These are the ones where you get two possible answers.

Never learned how to make circles using equations. Wasn't part of the Algebra 1 curriculum in NJ I suppose. Maybe we'll learn it this year.

School starts in a month and I have Algebra II Honors. This wasn't in the review.
Whelp, I loved factoring.

Went through algebra 1 but still don't know this. Maybe it's just because it's summer though

I learned this formula specifically in Geometry. (Actually I learned the standard form of (x + xoffset)^2 + (y + yoffset)^2 = r^2) This is, however, Algebra I-level math, the only geometry-level stuff would be knowing what the formula does.

do Not mention math

i dont even remember this i dont want to think about it

o u math is great

Starkiller · July 24, 2014, 04:22:44 AM

Wait but I dont see a circle. Find the radius of what?

seriously though I just finished pre algebra and this stuff looks creepy as forget.

I pitty da foo who deals with this kinda math on a daily basis
