Answer

$11+3x$

Work Step by Step

We start with the given expression: $(2+3x)+9$ The commutative property of addition states that changing the order of the addends does not affect the sum. We use this property to rearrange the addends: $9+(2+3x)$ The associative property of addition states that changing the grouping of the addends does not affect the sum. We use this property to group the addends differently: $(9+2)+3x$ We use the order of operations to simplify. We simplify inside the parentheses: $11+3x$
