Hey there!
2(x + y)
DISTRIBUTE 2 WITHIN the PARENTHESES
= 2(x) + 2(y)
= 2x + 2y
Therefore, your answer is: 2x + 2y
Basically, 2 (the first one) is your coefficient, x & y are your variables, and 2 (the second one) is your constant. Whereas, your addition symbol (the sum or +) is your operator.
Good luck on your assignment & enjoy your day!
