ok I understand, but how do you know that (n,m) is 6,4 and no other number?

so then we have $\frac{6}{4}$=1.5=K 6(1.5)=9 8(1.5)=12 $\therefore$ C is a similar to triangle ABC$\frac{8}{4}$=4=K 2*6=12 2*8=16 D) is similar to ABC $\frac{10}{4}$=2.5=K 2.5*6=15 2.5*8=20 E) is similar to ABC thank you very much for helping with this one.

thank you very much guys I think I almost got it. so to find the greatest even number that must be a factor of X I don't need to fin X. Right? then I don't need to find p and q. But then MarkFL how do you know that (m,n) is (6,4)=2

thanks I think I understand. however I wounder if thers a way to calculate the scaling factor? because how do you know which number to divide? In other words how do I find the number that divides 4,6,8 and gives 1,1.5,2

so we got to this point... given this equation $x=6{m}^{2}+4{n}^{2}$ what is the greatest even number that MUST be a Factor of X? taking m=2p and n=2q we have $x=6{\left(2p\right)}^{2}+4{\left(2q\right)}^{2}$ x=$x=6{\left(2{p}^{2}\right)}+4{\left(4{q}^{2}\right)}$...

I found this question in my study guide triangle ABC is similar to triangle DEF. Triangle ABC has sides 4,6,8. Wich could be the corresponding sides of a triangle DEF? Indicate all that apply A) 1, 1.5, 2 B)1.5, 2.25, 3 C)6, 9, 12 D) 8, 12, 16 E)10, 15, 20 What I did was add the...

well once you factor that expression... $$8\left(3{x}^{2}+2{y}^{2}\right)$$ buth then, how do I know what is the answer?

ok, I feel more confused... what I'm looking is X to be able to answer the question of What's the greatest EVEN number that is a factor of X. the hint you gave me is that I shoul find p and q which are co-primes but they aren't consecutive... my question would be p=1 and q=3 could be a...

Ok following that hint that you gave me, m=2p, n=2q I try giving values to p and q. I toke in consideration that p and q are co-primes, in other words, they must consecutive. p=2, q=3 x=6(16)+4(36) x= 96+144 x=1050 then I have that 1050 is X but how can I know that the values that I chose...

this one got me thinking for a while it starts like this: X=6m2+4n2 and Greatest Common Divisor(GCD) of (m,n)=2 what is the greatest EVEN number that must be a factor of X I started this question by thinking what they asked, the gratest number that is a factor of X then I need to calcualte X...

I see now I feel more confident saying that D) is the answer.

this is a nother problem from my study guide. it starts with a statement A) a/b B) 10/11 based on this information you have to choose an answer: a)quantity A is greater b)quantity B is greater c)the two are equal d)the relationship can not be...

We only consider 2 because is larger than one. Then we have 2>n/33 33*2= 66 66>n Any number less than 66 is value of “n” Thank you very much!

so are you saying that the only answer is 66 or that this is the only one that is not an answer?

I'm studying for the GRE and got stuck on this question Suppose "n" is a positive integer such that the smallest whole number that is greater than or equal to n/33 is 1 or 2. Wich are possible values for the integer n? indicate all such integers. a 15 b 24 c 50 d 66 e 77 what i start doing...
