Answer 1

Answer:

See explanation

Step-by-step explanation:

Consider the expression

$(5+29)+65$

First, use the commutative property over addition:

$(5+29)+65=65+(5+29)$

Then, use the associative property over addition:

$65+(5+29)=(65+5)+29$

Now, it is easy to add 5 and 65:

$65+5=70,$

so

$(65+5)+29=70+29=99$
