Answer:

See explanation

Step-by-step explanation:

Consider the expression

[tex](5+29)+65[/tex]

First, use the commutative property over addition:

[tex](5+29)+65=65+(5+29)[/tex]

Then, use the associative property over addition:

[tex]65+(5+29)=(65+5)+29[/tex]

Now, it is easy to add 5 and 65:

[tex]65+5=70,[/tex]

so

[tex](65+5)+29=70+29=99[/tex]
