What number does 3, 15, 5, and 9 go into evenly?
Well 3 and 5 go into 15 so you only need to worry about what 15 and 9 both go into.
15 = 3*5
9 = 3 *3
so 3*3*5 = 45 will be you answer
All multiples of 45 will work just fine :)
That sounds right to me but I don't know about vectors.
Can someone knowledgable take a lquick look at this query please. :))
I am not comfortable with your wording but if you mean what I think you mean than
r = sqrt(64+1)=sqrt(65)
Tan theta =8
And
Sin theta = -8/sqrt(65)

1) What to order? I found this really confusing. Melody

2) This is a simple vector question. Could someone knowledgable take a quick look please.

-2x^2+5x=0 what is the vertex for for this
This does not have a vertex because it does not equal y
however
y= -2x^2+5x
has a vertex at x= -b/(2a) = -5 / (2*-2) = 5/4
Sub in x=5/4 into the equation to find the value of y.
You are welcome .

Now I see that you asked 3 times!!
I think next time, if I see the questions quickly enough, I will white out all multiple asked questions.
So that there are no copies at all of it left on the forum. Not even ONE !!
DO NOT POST TWICE LIKE THIS!!
We are unlikely to get through all the questions today. Answering yours twice - now three times - means that 2, now 3, other peole will NOT get their question answered today!!!
BE THOUGHTFUL OF OUR TIME AND OTHER QUESTION ASKERS REQUIREMENTS PLEASE!!
What is negative six to the 2nd power minus (bracket) 56 divided by (parenthesis) negative 17 plus thirty one (parenthesis) (bracket) plus 25
You would have been better off just putting the bracket symbol that you wanted. Yours was confusing but I think this is what you wanted.
\(-6^2-(56/\{-17+31\})+25\\ =-6^2-(56/\{14\})+25\\ =-6^2-(4)+25\\ =-6^2-4+25\\ =-36-4+25\\ =-40+25\\ =-15\)
