Given polynomials p(x), g(x), and r(x),
p(x) + (q(x) +r(x)) = (P(x) + g(x)) +r(x)
To verify the associative property of addition,
begin by finding the sum of the polynomials:
(3x + 4) + ((5x2 - 1) + (2x + 6))
x2 + x

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

Use photo math it it’s so good

The scale factor of what ?
