If p is an odd integer and q is an even integer, which of the following must be an odd integer?	Pick one:
A) 2q+2p  B) 3(2p-q)  C) p^2+q^2  D) p+q+3  E) 5p-2q+1
p is odd; for this assume p=1   q is even; for this assume q = 2   (2*1)+(2*2)= 
<gadget id="calculator">(2*1)+(2*2)</gadget>
<output>6</output>
6 Even   3((2*1)-2)= 0 Even   1^2+2^2 = 5 Odd    1+2+3= 
<gadget id="calculator"> 1+2+3</gadget>
<output>6</output>
6 Even     (5*1)-(2*2)+1= 
<gadget id="calculator">  (5*1)-(2*2)+1</gadget>
<output>2</output>
2 Even   Answer:p^2+q^2
<result>C</result>
