Please help math question!

smallest triangle 5.7/11,
medium triangle 11/x
5.7/11=11/x
x=11*11/5.7≈21.2 (longer leg of the medium triangle)
difference between 6 and 5.7 is 6-5.7=0.3 ,

screen going to be 0.3 feet less, than leg of the medium triangle that was found
21.2-0.3=20.9 ft

$\dfrac{x+2}{2}=\dfrac{4}{5}\ \ \ \ \ |\text{cross multiply}\\\\5(x+2)=(4)(2)\ \ \ \ \ |\text{use distributive property}\\\\(5)(x)+(5)(2)=8\\\\5x+10=8\ \ \ \ |\text{subtract 10 from both sides}\\\\5x=-2\ \ \ \ \ |\text{divide both sides by 5}\\\\\boxed{x=-\dfrac{2}{5}}$

Factor out the GCF from the terms of the polynomial –4y5 + 6y3 + 8y2 – 2y. A. –2y4 + 3y2 + 4y – 1 B. y(–4y4 + 6y2 + 8y – 2) C. 2

Answer:

Option D) $-2y(2y^4-3y^2-4y+1)$ is correct

Therefore $-4y^5+6y^3+8y^2-2y=-2y(2y^4-3y^2-4y+1)$

Step-by-step explanation:

Given polynomial is $-4y^5+6y^3+8y^2-2y$

To factorise the given polynomial by taking out the common terms of the given polynomial :

$-4y^5+6y^3+8y^2-2y$
$=2y(-2y^4+3y^2+4y-1)$ ( here 2y is GCF common term so taking outside the terms of the polynomial )
$=-2y(2y^4-3y^2-4y+1)$ ( now taking (-) outside )

Therefore $-4y^5+6y^3+8y^2-2y=-2y(2y^4-3y^2-4y+1)$

Option D) $-2y(2y^4-3y^2-4y+1)$ is correct
