Which expression is equivalent to the expression below?
6r+3(3s+9r)
which one is it? SOS

Answer: 33r + 9s
Step-by-step explanation: First, we need to distribute
the 3 through both terms inside the set of parenthses.
Students will often multiply the 3 by the 3s but forget
to multiply the 3 by the 9r, beware of this mistake.
So we get 6r + 9s + 27r which simplifies to 33r + 9s.
The equivalent expression is 33r + 9s
The expression is given as:
6r + 3(3s + 9r)
Expand the expression
6r + 9s + 27r
Collect like terms
6r + 27r + 9s
Evaluate the like terms
33r + 9s
Hence, the equivalent expression is 33r + 9s
