8x2+6x-2 
I think! because 8,6, and 2 are all divisible by 2 
and 3. Factor the quadratic 
2(4x-1)(x+1)
        
             
        
        
        
(n - 2)*180 
Therefore, (8 - 2)*180
Which equals to 6(180) or 1080
Hope this helps! :)
        
             
        
        
        
Answer:
Step-by-step explanation:
a). Ratio of OP and RT = 
                                      = 
                                      = 
b). Since ΔOPQ ~ ΔRTS, their corresponding sides will be proportional.
     
     
     OQ = 
     OQ = 15 cm
c). m∠P = m∠T = 60°
d). m∠Q = m∠S
     By applying angle sum theorem in ΔRST,
     m∠R + m∠S + m∠T = 180°
     26° + m∠S + 60° = 180°
     m∠S = 180° - 86°
              = 94°
     Therefore, m∠Q = m∠S = 94°
