Answer:
AB = 2
Step-by-step explanation:
Using the secant- secant theorem, that is
PA × PB = PD × PC , substitute values
10(10 + AB) = 8(8 + 7)
100 + 10AB = 8 × 15 = 120 ( subtract 100 from both sides )
10AB = 20 ( divide both sides by 10 )
AB = 2
 
        
             
        
        
        
Answer:
21. 123    22. 6.86 or 6/ 6/7  23. 90
Step-by-step explanation:
21. (6+4)² + (22+10÷2) 
      (10)² + (22 + 5) 
         100 + 27
            127
22. (11+42-5) ÷ (11-4)
          48 ÷ 7
         6.85 or 6 6/7
23. (17-3) × (14 - 6) -22
          14 × 8 - 22
          112 - 22
            90
