Answer:
The sum of two even numbers is even and greater than the addends.
Step-by-step explanation:
Let 2n and 2m be two even numbers.
The sum of these numbers is
Use distributive property:
This number is even because 2 is its factor.
Note that
Thus, correct option is:
The sum of two even numbers is even and greater than the addends.
You would just divide 36 by 4 and 2. So you will need (4 to 2) an 18 to 9 ratio.
Answer:
The expression b/(a +b) does not exist when a = -b or b = -a
Step-by-step explanation:
The expression b/(a + b) does not exist if the denominator a + b = 0.
So, a = - b or b = -a.
So, the expression b/(a + b) does not exist when a = -b or b = -a.
When a = -b values, the denominator a + b = -b + b = 0. This will make the expression b/(a + b) = b/0 = ∞ which undefined or does not exist.
When b = -a values, the denominator a + b = a + (-a) = a - a = 0. This will make the expression b/(a + b) = -a/0 = -∞ which undefined or does not exist.
So the expression b/(a +b) does not exist when a = -b or b = -a
