1 answer:
Elan Coil [88]3 years ago
4 0

Answer:

<h2><em>a) inverse property</em></h2><h2><em>b) commutative property</em></h2>

Step-by-step explanation:

Property for Addition:

a + b = b + a - <em>commutative</em>

(a + b) + c = a + (b + c) - <em>associative</em>

a + (-a) = 0 - <em>inverse</em>

a + 0 = a - <em>identity</em>

<em></em>

We have:

a) 13 + (-13) = 0 → <em>inverse property</em>

b) (-12) + 16 = 16 + (-12) - <em>commutative property</em>

<em></em>
