Answer
$x+7$
Work Step by Step
We start with the given expression: $(4.4\div4.4)(x+7)$
We use the order of operations to simplify:
First, we simplify inside the first set of parentheses: $1\times(x+7)$
The identity property of multiplication states that the product of any real number and $1$ is the original number.
We use this property to simplify the expression: $x+7$
