D. The elevator takes 37.5 seconds to move down to the lobby.
8x+y=300
y= 300-8x
y= 300 - 8 (37.5)
y = 300-300
y = 0
wheb y =0 that means that the height is 0
Use this 3 following steps:
1)At first, we should find the roots :
3x+8=0 => x=-8/3
x-4=0 => x=4
2)Using a chart for the limits:

3)choose your solution:
[-8/3,-4)==> Sentence 3 is correct

Answer:
Step-by-step explanation:
<u>According to the question we have:</u>
- Formula h = - 16t + s
- h = 0
- s = 555.427 ft
- t = ?
<u>Substitute the given values and solve for t:</u>
- 0 = - 16t + 555.427
- 16t = 555.427
- t = 555.427/16
- t = 34.714
The answer by the sequence:
Width of the garden = w
Length of the garden = 2w+3
Width of the entire plot = w + 0.5w = 1.5w
Length of the entire plot = (2w + 3) 0.5w = 2.5w + 3
Area of the garden = w (2w + 3)
Area of the entire plot = 1.5w (2.5w + 3)
Area of the garden = 2w² + 3w
Area of the entire plot = 3.75w² + 4.5w
Area of border = area of the entire plot - area of the garden
= 3.75w² + 4.5w - (2w² + 3w)
Area of the border = 3.75w² + 4.5w - 2w² - 3w
Area of the border = 1.75w² + 1.5w
