The distributive property states:
[tex]a(b+c) = ab + ac[/tex]
Using that we get:
[tex]5\times (3+4)\\5(3+4) \\5(3) + 5(4)\\15 + 20\\35[/tex]
You could also do it like:
[tex]5(3+4)\\5(7)\\35[/tex]
So an expression that is equivalent to 5(3+4) is:
[tex]7(2+3)[/tex]
That is your answer. It gets you the same final answer of 35.
Hope that helped :)
