Which one of the following equations illustrates the commutative property? 8 + 3 = 4 + 7 if 3 + 5 = a, then a = 3 + 5 2 + b = b + 2 3(2 + 5) = 6 + 15

2 + b = b + 2

Step-by-step explanation:

Commutative property states that

a+b = b+a

changing the order of terms will not affect the equation

8 + 3 = 4 + 7

Here the order is not changed, the numbers are changed

So the above equation does not illustrates commutative property

If 3 + 5 = a, then a = 3 + 5

3+5 = 3+5, here the order is not changed

the above equation does not illustrates commutative property

2 + b = b + 2

Here the order of terms are changed. It does not affects the equation

the above equation illustrates commutative property

3(2 + 5) = 6 + 15

In this equation the distributive property is used

3 is distributed inside the parenthesis

the above equation does not illustrates commutative property

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
