**bobpursley**, Tuesday, September 28, 2010 at 1:24pm2a + sqrt (2a^2)=10

a(2+sqrt2)=10

a=10/(3.141) - math subject (correction) -
**PsyDAG**, Wednesday, September 29, 2010 at 12:14pmSquare root of a^2 = a

Factor out a.

a(2 + sqrt2) = 10

Sqrt 2 = 1.4142 = 1.41

a(2 + 1.41) =**3.41**a = 10

Divide both sides by 3.41.

x = 10/3.41 = 2.93
