Answer:
−0.8x2+4.2x+5.49878
Step-by-step explanation:
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:
22
Step-by-step explanation:
The average of the 6 even integers is the odd integer halfway between the first three and the last three. That average value is 126/6 = 21, so the 4th integer is 21+1 = 22.
_____
All 6 are {16, 18, 20, 22, 24, 26}.
Add 3.2 to both sides
Simplify -20.7 + 3.2 to -17.5
Multiply both sides by 7
Simplify -17.5 x 7 to -122.5
Switch sides
Answer: y = -122.5.
