**HELP HELP HELP MNHS**, Monday, February 4, 2013 at 5:31amx 1st + even integer

x+2 2nd + even integer

x^2+(x+2)^2= 164

x^2+x^2+4x+4-164=0

1/2(2x^2+4x-160=0)

x^2+2x-80=0

(x+10)(x-8)=0

x=-10 & x=8, disregard -10 since we are looking for positive integers...

so, x=8 (1st even)

x+2= 10 (2nd even)
