#### Work Step by Step

$[c(2+3b)]5\longrightarrow$ Use the distributive property.
$[c(2)+c(3b)]5\longrightarrow$ Use the commutative property.
$(2c+3bc)5\longrightarrow$ Use the distributive property.
$10c+15bc$
Since known properties can be used to translate the first expression to the second the expressions are equivalent.
