Which expressions are equivalent to (5⋅x)⋅3 ? drag and drop the equivalent expressions into the box. 3⋅(5⋅x) 5⋅3+x⋅3 5⋅(x⋅3) 15x 5⋅3⋅x⋅3

3⋅(5⋅x)

5⋅(x⋅3)

15x

Step-by-step explanation:

As the values are inside the brackets, it does not matter what side the (x3) is on, so 3⋅(5⋅x) is equivalent.

Multiplying the contents of the brackets in the third one (x * 3) by 5 gives the same value as 3 * (x * 5) so 5⋅(x⋅3) is also equivalent.

On multiplying the brackets out:

5 * x = 5x

5x * 3 = 15x

So 15x is also equivalent.
