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