Drag each expression to the correct location on the table. Not all expressions will be used.
Determine if each expression is equivalent to an expression in the table. Place the expressions that are equivalent in the correct column.
2x + 2y + (2x + y)
4x + 4y - y
2x + 6 + x + 3
2x + 2y + 2x
2x - x + 7x
7x + x + 0 · y
y + 3x - y + 9
5(2x) - 2x

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
