The expression below was simplified using two properties of operations 5(11z+29+6z) which properties were applied in steps 1 and 3, respectively

Associative property, then distributive property

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

step 1 5(11z+6z+29)

step 3 85z+145  

My

=5(11z+29+6z)

=5(17z + 29)

=5(17z + 29)

=5(17z) + 5(29)

= 85z + 145

Hope it will find you well.
