Respuesta :
we know that
The Associative Property Of Addition states that
[tex]a+(b+c)=(a+b)+c[/tex]
in this problem we have
[tex]a=2 \\b=\sqrt{5}\\c=7[/tex]
substitute in the formula above
[tex]2+(\sqrt{5}+7)=(2+\sqrt{5})+7[/tex]
therefore
the answer is the option
B: Associative Property Of Addition
