Answer 1

C (distributive and addition properties)

Explanation:

For Edg test

Answer 2

Distributive and addition properties

Explanation:

We are given that an expression

`5x+x-2`

Which is equivalent to
`6x-2`

The expression can be written as

`(5+1)x-2`

Using distributive property

`a\cdot(b+c)=a\cdot b+a\cdot c`

Now, using addition property of integers

We get

`6x-2`

Hence, the option C is true.
