The products that result in a perfect square trinomial is (x + y + x)(x + y + x), (2x - 3)(-3 + 2x) and (4y² + 25)(25 + 4y²)
<h3>What is an
polynomial?</h3>
A polynomial is an expression that involves only the operations of a<em>ddition, subtraction, multiplication</em> of variables.
A perfect square trinomial is the square of a binomial
(x + y + x)(x + y + x) = (2x + y)²
(2x - 3)(-3 + 2x) = (2x - 3)²
(4y² + 25)(25 + 4y²) = (4y² + 25)²
The products that result in a perfect square trinomial is (x + y + x)(x + y + x), (2x - 3)(-3 + 2x) and (4y² + 25)(25 + 4y²)

Answer:
A
Step-by-step explanation:
A is the correct answer. This is an example of using the distributive property by removing the brackets. You can see it if you break it down to two groups.
Group one: 4 * 2
Group Two: 4*5
You could easily combine these, but this exercise was intended to lead you into algebra. The two groups are separated by a plus sign.
4*2 + 4*5
C. 402
323.24 rounded = 323
79.13 rounded = 79
323 + 79 = 402
Compare the impure one, with the rest of the pure gold ones.
