In a circle, the arc is two times the length of the angle.
EFG = 98°
98 x 2 = 196
Minor arc EG = 196°
Hopefully this helps :)

We can solve this using the FOIL method.
= (7x + 3)(7x - 3)
= (7x * 7x) + (7x * -3) + (3 * 7x) + (3 * -3)
= 49x - 21x + 21x - 9
= 49x - 9
Hope This Helped! Good Luck!
 
        
             
        
        
        
Red line shows
y=x^2-4 , cause it's going through point (0,-4)
So blue line shows 
y= -x^2+1 Point (1,0) belong to it , moreover x factor is negative , so the arms of parabola will go down
Have nice evenig :)
