Answer:
X to the second power + 5x + 6
Step-by-step explanation:
distribute (X + 2) and (X + 3)
you should get X to the second power + 3x + 2x + 6
then you add like terms (3x + 2x) 
then you should get X to the second power + 5x + 6
 
        
                    
             
        
        
        
The sum of angle around a point equal 360° 
so (BOA) = 360-250=110° 
and the sum of angle in the shape CAOB = 360° 
so BCA = 360-(110+90+90)= 70°
THE ANSWER IS C.70°
