Question

3. Which statement illustrates the inverse property

of addition?
A. a + 4 = a + (-4)
B. a + (-7 + 7) = a +0
C. a + (a + 2) = a + (-a-2)
D. -a(5+3) = -5a + (-3a)

Answer 1

B

Explanation:

B. a + (-7 + 7) = a +0

When you remove a from both sides, you're left with -7+7=0 which shows that the opposites of the numbers add up to 0.
