Answer:</h2>
For a real number a, a + 0 = a.  TRUE
For a real number a, a + (-a) = 1.  FALSE
For a real numbers a and b, | a - b | = | b - a |.  TRUE
For real numbers a, b, and c, a + (b ∙ c) = (a + b)(a + c).  FALSE
For rational numbers a and b when b ≠ 0, is always a rational number. TRUE
<h2>Explanation:</h2>
- <u>For a real number a, a + 0 = a.  </u><u>TRUE</u>
This comes from the identity property for addition that tells us that<em> zero added to any number is the number itself. </em>So the number in this case is  , so it is true that:
, so it is true that:

- For a real number a, a + (-a) = 1.  FALSE
This is false, because:

For any number  there exists a number
 there exists a number  such that
 such that 
- For a real numbers a and b, | a - b | = | b - a |.  TRUE
This is a property of absolute value. The absolute value means remove the negative for the number, so it is true that:

- For real numbers a, b, and c, a + (b ∙ c) = (a + b)(a + c).  FALSE
This is false. By using distributive property we get that:

- For rational numbers a and b when b ≠ 0, is always a rational number. TRUE
A rational number is a number made by two integers and written in the form:
 
 
Given that  are rational, then the result of dividing them is also a rational number.
 are rational, then the result of dividing them is also a rational number.
 
        
        
        
True.
 The diameter is the axis of symmetry of a circle.
 The diameter divides the circle into two equal parts. Therefore, it can be considered an axis of symmetry. Everything on the right of the diameter is the same as everything on the left of the diameter.
 answer
 True.
