Question 926259
<pre>
First odd number = x
Second odd number = x+2
Third odd number = x+4

{{{sqrt(x+(x+1)+(x+4))}}}{{{""=""}}}{{{12}}}

Square both sides.  When you square a square root
you take away the square root radical:

{{{x+(x+2)+(x+4)}}}{{{""=""}}}{{{12^2}}}

{{{x+x+2+x+4}}}{{{""=""}}}{{{144}}}

{{{3x+6}}}{{{""=""}}}{{{144}}}

Add -5 to both sides

{{{3x)}}}{{{""=""}}}{{{138}}}

{{{x}}}{{{""=""}}}{{{46}}}

First odd number = x = 46
Second odd number = x+2 = 46+2 = 48
Third odd number = x+4 = 46+4 = 50
