5(4n-1)^2 +23(4n-1)-10
5(4n-1)^2 +25(4n-1)- 2(4n-1)-10
5(4n-1)(4n-1+5)- 2(4n-1+5)
(4n-1+5) (5(4n-1)-2)
(4n+4) (20n-5-2)
4(n+1) (20n-7)

Step-by-step explanation:
The brake horsepower of an engine that’s being tested is coupled to a dynamometer that has a radius arm of 1.70 feet is letter D. 170.
As the sides shown are same so the base of large triangle is double the base of smaller triangle
That is
2(3x-8) =20
Divide both sides by 2
3x-8 = 10
Add 8 to both sides
3x =18
Divide both sides by 3
x=6
So answer is 6.0
