Anybody good at math?

I'm awful but have this test tomorrow... i think its pretty basic..i just need to know if im doing it right..

X = 1.4
Y= 3.1
Z = 3.8

work out the following..

X=YZ =

X (X=Z - 2Y) =

X-squared (Y-squared + Z-squared) =

any help would be appreciated..workings out too

guess not

i have an A-Level in Maths but this makes no sense to me sorry buddy

thanks anyway... on planetswans they just told me to use my 12 fingers and count.... i was like

this really makes no sense. can you atleast scan the exersize?

my spelling sux

this really makes no sense. can you atleast scan the excersize?

the sample test is online...im shut out of my photobucket though so i cant upload.

the answer to X + YZ = -10.39 i just dont know how the feck they got that...

Yz means y x z so 3.1 x 3.8 which is 11.78 so the answer to x + yz would be 1.4 + 11.78 which is 13.18 so question must x - yz which gives 1.4 - 11.78 = -10.38 or if one of y or z is a minus number since a +number times a minus number gives minus answer,

Mate - the questions make no sense

X is 1.4
YZ means Y times Z which is 11.78

So can't see how you can get that answer as to me it would be 1.4 (X) + 11.78 (Y x Z) = 13.18

Even if you took it away it'd be 10.38

Sorry I can't help more

oh damn, now i get it.

I'm awful but have this test tomorrow... i think its pretty basic..i just need to know if im doing it right..

Y= 3.1
Z = 3.8

work out the following..

X=YZ =
Yz means y x z so 3.1 x 3.8
X (X=Z - 2Y) =
Z - 2 x y, work out 2 x 3.1 first which is 6.2 then z - 6.2 which is 3.8 - 6.2 = - 2.4
X-squared (Y-squared + Z-squared) =y squared means y x y so 3.1 x 3.1 =9.61, z squared z x z which means 3.8 x 3.8 = 14.44 then cos + in middle , 9.61 + 14.44= 24.05. Hope this helps ,

It must be a typo.. University of Glamorgan for you folks. Thanks for the help

Thanks alot blue

hold it...I thought this was much, much complex than it actually is. 7grader wouldnt have problems with this one, and I'm just overthinking basterd wow Im so stupid

i did say it was easy..the whole module is a joke but i couldnt figure out what they were doing..

Good luck with test

I think the answer to the third one is not 24.05, but 47.138, don't ask me why, I can't explain that

it is

What a bunch of thick twats we are

Chaps, off the top of my head try this:

X Squared is 1.96.
Y sqaured is 9.61.
Z squared is 14.44

Y squared + Z sqaured = 14.44

Multiplied by the sqaure of X gives you 47.138 ...

Elementary.

Yes definitely 47. ..., didn't see the bracket. as coops said work out bracket first then times by x squared,

No you need Claire the resident Carol Vordaman
