Use the associative property to create equivalent expressions to a + b + (c + d). Which statements are true? Select four options.

The associative property of addition lets you change how addends are grouped without changing their order or the sum. Thus, a + (b + c) + d and (a + b) + c + d are both equivalent to a + b + (c + d). The other expressions use multiplication, so they are not equivalent by regrouping addition.
