Answer:
One of the equivalent expressions is [tex]2(j+k)[/tex].
Step-by-step explanation:
In the expression
[tex]j+j+2k[/tex]
there are 2 [tex]j's[/tex] ;therefore, the expression can be rewritten as
[tex]2j+2k[/tex],
and using the reverse distribute property which says
[tex]ax+ay=a(x+y)[/tex],
we rewrite our expression as
[tex]2j+2k = \boxed{2(j+k).}[/tex]
