$(x+3)5$
Work Step by Step
RECALL:
The commutative property of multiplication states that for any real numbers $a$ and $b$,
$ab=ba$
If you apply the commutative property of multiplication to $5(x+3)$. you'd get $(x+3)5$ as an equivalent expression.
Thus, the given algebraic expression is equivalent to:
$(x+3)5$
