Respuesta :

answer is A) 4x + (7y + 5z) ....switching grouping....result will be the same.

Answer: (A) 4x+(7y+5z).


Step-by-step explanation:  The given expression is (4x+7y)+5z.

For the set of real numbers, we have the following associative property-

If a, b and c are any three real numbers, then  [tex](a+b)+c=a+(b+c)[/tex]

Applying this associative property of real numbers, we can write

[tex](4x+7y)+5z=4x+(7y+5z)[/tex]

So, options (B), (C) and (D) are incorrect.

Thus, the correct option is (A).
