Which products result in a perfect square trinomial? check all that apply. (x + 9)(x 9) (xy + x)(xy + x) (2x 3)(3 + 2x) (16 x2)(x2 16) (4y2 + 25)(25 + 4y2)

(xy + x)(xy + x)(16 x2)(x2 16) (4y2 + 25)(25 + 4y2)

Step-by-step explanation:

The product of two identical binomial factors will be a perfect square trinomial. The appropriate answer choices are those having both factors the same.

Rounding decimals is very similar to rounding other numbers. if the hundredths and thousandths places of a decimal is forty-nine or less, they are dropped and the tenths place does not change. for example, rounding 0.843 to the nearest tenth would give 0.8. , your welcome !
