Step-by-step explanation:
there ya go:)
I believe the answer could be 13n.
1) 5 + ( 2 + 7) = (5 + 2) + 7
It is the associative property of the addition.
This property states that when adding 3 numbers, the grouping or association of the numbers does not change the result.
2) <span>The second expression is unreabable
</span>
<span>3) h + 0 = h
</span>
<span>It is the identity property.
</span>
This property states that 0 is the identity element of the addition and any number added to it is equal to the same number.
AS you know, 5 + 0 = 5, 1234 + 0 = 1234; 0 + 2548 = 2548.
Your answer is 67 hope this helps
