Answer:
104
Step-by-step explanation:
This is not a distributive property question though.
A distributive property has a number (a) outside the parenthesis
a(b+c)
so in this case a(40+64)
then you would multiply a by both numbers
40a+64a
then add them together
104a
However if it is a number outside the parenthesis and not a variable, it will come out different
For example 
5(40+64)
(5*40)+(5*64)
200+320
520
Hope this helps!
