Question 958321: Please help me solve this problem:
a) Compute x+y and sqrt(x^2+y^2) when x=5 and y=12.
b) When is
x+y=sqrt(x^2+y^2)
When is
x+y not equal to sqrt(x^2+y^2)
Thank you so much! I hope you can get back on me soon.

You can put this solution on YOUR website!

a) Compute x%2By and sqrt%28x%5E2%2By%5E2%29 when x=5 and y=12.
x%2By=5%2B12=17
sqrt%28x%5E2%2By%5E2%29=sqrt%285%5E2%2B12%5E2%29=sqrt%2825%2B144%29=sqrt%28169%29=13
b) When is
x%2By=sqrt%28x%5E2%2By%5E2%29
5%2B12=sqrt%285%5E2%2B12%5E2%29
17=13.......not true statement
When is
x%2By+%3C%3E+sqrt%28x%5E2%2By%5E2%29
17+%3C%3E+13.........true statement
