Which expression illustrates the associative property of addition?(3 + 19) – 12 = (3 + 12) – 193 + (19 – 12) = 3 + (19 + 12)(3 + 19) – 12 = 3 + (19 – 12)3 + (19 –12) = 3 – (19 + 12)

Answer: THIRD OPTION.Step-by-step explanation: The Associative property of addition states that when three or more numbers are added, it does not matter how they are grouped, the sum is the same. Then: [tex]a + (b + c) = (a + b) + c[/tex] Based on this and having the expression [tex]3 + 19- 12[/tex], we can apply the Associative property as following: [tex](3 + 19) - 12 = 3 + (19 - 12)[/tex] Therefore, the  expression that illustrates the Associative property of addition is the one shown in the Third option.
