Answer:
w ≥ 1
Step-by-step explanation:
Given
5w ≥ - 6w + 11 ( add 6w to both sides )
11w ≥ 11 ( divide both sides by 11 )
w ≥ 1

Step-by-step explanation:
The falling leaves and the draining of the pool signal an end and parallel the end of the illusion and the end of Gatsby's life.
Given that the area is equal to twice the perimeter and the dimensions are:
length=4x ft, width=(x+6) ft
the perimeter will be:
P=2(L+W)
P=2(4x+(x+6))
P=2(4x+x+6)
P=2(5x+6)
P=(10x+12)
Area of the rectangle is:
A=4x(x+6)
A=4x²+24x
but:
2P=A
thus
2(10x+12)=4x²+24x
20x+24=4x²+24x
thus
4x²+4x-24=0
x²+x-6=0
x²-2x+3x-6=0
x(x-2)+3(x-2)=0
(x-2)(x+3)=0
thus the answer is:
x=-3 or x=2
thus
length=4x=4*2=8 ft
width=(x+6)=(2+6)=8 ft
