Answer:
24. (-35) - (-23) = -12
25. 7 * 6 + (-8) + (21) = 55
26. 2x + 4 = 4 + 2x Commutative Property of Addition
27. 5a(x + 7) = x + 35a Distributive Property of Multiplication over Addition
28. (m + n) + o = m + (n + o) Associative Property of Addition
29. (ab + bc) = (a + c)b Associative Property of Addition
30. (97)(1) = 97 Multiplicative Identity
Note; Kindly correct me if I'm wrong. :)
