what error did shena make?
shena should have written the associative property for step 1.
shena should have written the associative property for step 2.
shena should have written the associative property for step 3.
shena should have written the associative property for step 4.

2.

Shena should have written the associative property for step 2.

Step-by-step explanation:

1. Commutative property says So, we can use this property to rewrite the expression as

True.

2. Associative property says This means we can put brackets to determine convinient order of operations. Here, in step 2, Shena should use associative property to get

False.

3. Distributive property that So,

True

4. Addition property gives that and so

True.

the cat is blue because the probability of extension towards the prefix of the diameter of the circle could only mathematically equal to the sum of the roots of the carrots from   your garden.
