Question

Which expressions are equivalent to z + (z + 6)z+(z+6)z, plus, left parenthesis, z, plus, 6, right parenthesis ?

question- z+(z+6)=

Answer 1

`2(z+3)`

Explanation:

We are given that the expression

`z+(z+6)`

We have to find the expression which is equivalent to given expression.

`z+z+6`

To find the equivalent expression we will combine like terms

Now, combine like terms we get

`(z+z)+6`

`2z+6`

By using the property

`a+a+..+a(n times)=na`

Therefore, the expression we get

`2z+6`

Now, taking common 2

`2(z+3)`

Hence, the expression which is equivalent to given expression is given by

`2(z+3)`
