Answer:

A. Commutative Property of Addition

Step-by-step explanation:

Given equation,

9 + 8 = 8 + 9

If a and b are any real numbers,

By the commutative Property of Addition

a + b = b + a

By the identity Property of Addition

a + 0 = a

By the distributive Property,

a(b+c) = ab + ac

By the associative property of addition,

a + (b + c ) = (a + b) + c

Hence, OPTION A is correct.

Answer:

Commutative Property of Addition

Step-by-step explanation:

I assume you mean 9+8=8+9

In that case it is the Commutative Property of Addition.

That means you can switch the numbers around and it will stay the same value.
