Answer this question for me plz i really need on this

19. (a-b)/d...a = -2, b = 3, c = 6 and d = 1/3
(-2 - 3) / (1/3) =
-5/(1/3) =
-5 * 3 = -15 <==

20. -a(b + c) =
   -2(3 + 6) =
    -2(9) =
     -18 < ==
   
22. (a - b + 3d)/b
      (-2 - 3 + 3(1/3) / 3 =
      (-5 + 1)/3 =
       -4/3 <===

23. b - a^2
      3 - (-2^2) =
      3 + 4 =
      7 <===

25. ab^2 =
      -2 * 3^2 =
      -2 * 9 =
     -18 <===

26. -(b-c)^2
      - (3 - 6)^2 =
      -(-3)^2 =
        -9 <==
