MHB Find the Sides of Triangle DEF: A Challenge!
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.- CharlesLin

MHB Finding the Greatest EVEN Factor of X: Solving the GCD of m,n=2
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- CharlesLin

MHB Find the Sides of Triangle DEF: A Challenge!
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- CharlesLin

MHB Finding the Greatest EVEN Factor of X: Solving the GCD of m,n=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=$x=6{\left(2{p}^{2}\right)}+4{\left(4{q}^{2}\right)}$...- CharlesLin

MHB Find the Sides of Triangle DEF: A Challenge!
I found this question in my study guide triangle ABC is similar to triangle DEF. Triangle ABC has sides 4,6,8. which 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...- CharlesLin

MHB Finding the Greatest EVEN Factor of X: Solving the GCD of m,n=2
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?- CharlesLin

MHB Finding the Greatest EVEN Factor of X: Solving the GCD of m,n=2
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...- CharlesLin

MHB Finding the Greatest EVEN Factor of X: Solving the GCD of m,n=2
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...- CharlesLin

MHB Finding the Greatest EVEN Factor of X: Solving the GCD of m,n=2
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 calculate X...- CharlesLin

MHB Solve the a/b and 10/11 Problem: Understanding Quantity Relationships
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...- CharlesLin

MHB GRE: Solving "n" Integer Question: Determining Possible Values
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!- CharlesLin
