The property in the expression 4 + (x + y) = (4 + x) + y is Commutative property.
<h3>What is the number?</h3>
A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
It is given that:
4 + (x + y) = (4 + x) + y
As we know,
Commutative property is the property in which we can arrange the terms withouth changing the sign.
For an example:
a + b = b + c
In the given expression
4 + (x + y) = (4 + x) + y
The Commutative property is applied to rearrange the terms.
Thus, the property in the expression 4 + (x + y) = (4 + x) + y is Commutative property.

B.)greater than five but less than six
Answer:
Step-by-step explanation:
x2-9 = 0
Area of one dimension = x-3= 0
So, x2= 9
Square root on both sides;
x= +3 and -3
x-3 is one side
x+3 is the other dimension
