Question

Which expressions are equivalent to j+j + 2k

Answer 1

The correct answer is:

None of the above

Answer 2

One of the equivalent expressions is
`2(j+k)`.

Explanation:

In the expression

`j+j+2k`

there are 2
`j's` ;therefore, the expression can be rewritten as

`2j+2k`,

and using the reverse distribute property which says

`ax+ay=a(x+y)`,

we rewrite our expression as

`2j+2k = \boxed{2(j+k).}`
