Options (2), (3) and (5)

Step-by-step explanation:

This question is incomplete; here is the complete question.

Which products result in a perfect square trinomial? Select three options.

1). (-x + 9)(-x - 9)

2). (xy + x)(xy + x)

3). (2x - 3)(-3 + 2x)

4). (16 - x²)(x²+ 16)

5). (4y² + 25)(25 + 4y²)

Option (1),

(-x + 9)(-x - 9) = -(-x + 9)(x + 9)

Therefore, product is not a perfect square.

Option (2)

(xy + x)(xy + x) = (xy + x)²

So the product is a perfect square trinomial.

Option (3)

(2x - 3)(-3 + 2x) = (2x - 3)²

Therefore, product is a perfect square trinomial.

Option (4)

(16 - x²)(x²+ 16) = (-x⁴+ 256)

Therefore, product is not a trinomial.

Option (5)

(4y² + 25)(25 + 4y²) = (4y² + 25)²

                                = 16y⁴ + 200y² + 625

Therefore, product is a perfect square trinomial.

Options (2), (3) and (5) are the correct options.

a .4y4

hope this !

it's 100

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

  n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the  14th  row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)
