Question

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

Answer 1

First, the commutative property was used because to change the order inside the parentheses before adding. 
then the distributive property was used to distribute the 5 by multiplying. Hope this helps!

Answer 2

Answer:

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 answer:

• Associative allows the combining of like terms (Both with variable z)

=5(11z+29+6z)

=5(17z + 29)

• Distributive allows the 5 to distribute through

=5(17z + 29)

=5(17z) + 5(29)

= 85z + 145

Hope it will find you well.
