Answer:
12
Step-by-step explanation:
This is an example of Addition property between two positive integers (i.e. whole value numbers), which means the result will be positive and larger than the two numbers.
The result of the addition would be:
[tex]5 + 7 = 12[/tex]
Another way to do it if you are struggling a bit you can write the value of [tex]7[/tex] as [tex]7 = 5 +2[/tex] so then you can say:
[tex]5 + (5 + 2) = 5 + 5 + 2 = 10 + 2 = 12[/tex]
