Question

Which expression is equivalent to n (2 + 5)? A. 2 - (5. n) B (2 + n) - 5 C. (5 + 2). D. (5. n) + 2

Answer 1

Commutative property: The numbers on which we operate can be moved or swapped from their position whitout makin any difference to the answer. This property holds for addition and multiplication.

As the given expression is:

`n\cdot(2+5)`

You can change the position of the numbers that are being adding to get (5+2) and then change the position of factors (terms that are multiplied) to get:

`(5+2)\cdot n`
