Explanation:
the cards show n² + 3² = n² + 9
but (n + 3)² = n² + 6n + 9.
so, 6n is missing in the cards.
therefore Andy is right.
Answer:
Andy is right.
( n + 3 )²
n² + 6n + 9
here Justin arranged cards in this way : n * n = n² and 9 * 1 = 9
so it gives the card equation n² + 9
n² + 6n + 9 - (n² + 9 )
6n
∵ Therefore its wrong and does not match. Andy really figured its wrong.
