Nathaniel and Jonathan are asked to write an expression equivalent to 3(3x+3y).

Nathaniel writes the expression 9x+9y

Jonath writes 18xy

Who is correct and why?

• Nathaniel is correct becuase 3(3x)+3(3y)=9x+9y

• Nathaniel is correct becayse 3+3x+3+3y=9x+9y

• Jonathan is correct because $3\times3x\times3y=8xy$

• Jonathan correct because 3(6xy)=18xy
