Which expressions are equivalent to (4⋅a)⋅2 ? drag and drop the equivalent expressions into the box.4⋅(a⋅2)2⋅(4⋅a) 4⋅2⋅a⋅28a 4⋅2+a⋅2

4⋅(a⋅2)  

2⋅(4⋅a)

8a

Step-by-step explanation:

(4⋅a)⋅2

4⋅(a⋅2)  This is the same by the  associative property of multiplication

2⋅(4⋅a)  This is the same by the  associative property of multiplication and the communicative property of multiplication

4⋅2⋅a⋅2   This brings in an extra 2 so it is not the same.

8a    4*2 = 8 so this is the same

4⋅2+a⋅2  This is the not the same   8+2a  is not the same as 8a
