Answer 1

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 2

Andy is right.

Explanation:

( 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.
