use the properties of operation to add g-2 + g+2
5g
5g - 10
5g - 6
5g + 10
The correct answer is 5g.
To add g-2 + g+2, we can use the commutative property of addition, which states that changing the order of the numbers being added does not affect the sum.
Therefore, we can rearrange the expression as (g+2) + (g-2).
Using the distributive property of addition, which states that a + b + c = a + (b + c), we can combine like terms within each set of parentheses.
(g+2) + (g-2) = (g+g) + (2-2) = 2g + 0 = 2g
So, g-2 + g+2 simplifies to 2g.
