find the value of x can somebody tell me if i did it right the picture is attached (x+4)*4=(5+3)*3 4x*4=8*3 4x*4=24 -4 -4 4x=20 4x/4 =20/4 x=5

OpenStudy (dan815):

no

OpenStudy (anonymous):

OpenStudy (dan815):

the 2nd line is wrong

OpenStudy (anonymous):

why?

OpenStudy (dan815):

(x+4) *4 = 4x+16

OpenStudy (anonymous):

yeah but arent we supposed to solve in the parenthesis first?

OpenStudy (dan815):

you cant solve x+4 any further

OpenStudy (anonymous):

ohh but the second part 5 3 can be so we dont have to do what we did for the first one right

OpenStudy (dan815):

what u said was if i add 4 to something then thats the samething as multiplying it by 4 is that true??

OpenStudy (anonymous):

no thats not

OpenStudy (dan815):

so u cant say x+4 = 4x

OpenStudy (dan815):

u silly goose

OpenStudy (anonymous):

(x+4)4=(5+3)3 4x+16=24 -16 -16 4x=8 4x/4=8/4 x=2

OpenStudy (dan815):

everything else looks good does your question say that the smaller line is 3/4th the size of the other one

OpenStudy (anonymous):

lolz n o the question only ask for the value of x

OpenStudy (dan815):

look at your value for x and the diagram makes more sense right? if it was 5 itd be way too big

OpenStudy (dan815):

how did you get that formula to solve for X :O

OpenStudy (anonymous):

its a theorem (A+B)*B=(C+D)*D

OpenStudy (anonymous):

yes it does make more sense the line is shorther then the other line which is 5

OpenStudy (dan815):

interesting

OpenStudy (dan815):

circles are very interesting creatures

OpenStudy (anonymous):

i dont like them lol they ve given me alot of trouble

OpenStudy (dan815):

lol

OpenStudy (dan815):

me too

OpenStudy (dan815):

but they grow on you

OpenStudy (anonymous):

once u get to understand it then they do when u start off knowing nothing it seems really hard

OpenStudy (dan815):

u will never fully understand circles lol, i am in college and they still get me

OpenStudy (anonymous):

lol i was supposed to be in college but a few subjects r holding me bak lol

OpenStudy (dan815):

ah just wait lol, even in engineering mathematics circles are a feather... u have to integrate over them find ways to represent circles in patermetrization and all this BS

OpenStudy (dan815):

lol it censored B**CH

OpenStudy (anonymous):

omg lool i like triangles the simple ones that u cd solve with the pythagorean theorem im a master in that lool

OpenStudy (dan815):

hahaha in our math right now we forgot about x y z axis now its all about sphere axis some angles and radius this is what we work on
