Question 277568
{{{x+y=25}}} "the sum of two positive integers is 25"
{{{x^2+y^2=275}}} "The difference of their squares is 275"
id use the elimination method

{{{x+y=25}}} = {{{x^2+y^2=25^2}}} = {{{x^2+y^2=625}}}
{{{x^2+y^2=275}}}
well doesnt come out well at all so i did guess and check and 12&13,11&14,10&15,9&16,dont work and 17^2 by itself is more than 275  so there is no answer since they are looking for integers and not decimals


<p>
L=5W
a=LW
66=5WW
{{{66=5W^2}}}
{{{66/5=W^2}}}
{{{sqrt(66/5)=W}}}
L=5W
{{{L=5(sqrt(66/5))}}}
