To determine the perimeter of the rectangular flower garden, we need to know the measurement of the sides of the rectangle so we have to know the length and the width. The given measurements are the area, and the relation of the width and the length. From these, we generate equations to calculate the width and the length. We do as follows:
Area = Length x Width
where length = x ft
width = x - 4 ft
area = 32 ft^2
32 = x (x -4)
32 = x^2 - 4x
Solving for the positive value of x,
x = 8 ft = length
width = x -4 = 8 - 4 = 4 ft
Perimeter = 2(length) + 2(width) = 2(8) + 2(4) = 24 ft

Answer:
1. x^2-9x+18
2. 2x^2-4x-16
3. 3x^2-19x-14
4. 6x^2 +14x + 8
Step-by-step explanation:
1. (x-3)(x-6)
x^2 - 6x - 3x +18 = x^2-9x+18
2. (2x+4)(x-4)
2x^2-8x+4x-16 = 2x^2-4x-16
3. (x-7)(3x+2)
3x^2+2x-21x-14 = 3x^2-19x-14
4. (3x+4)(2x+2)
6x^2+6x+8x+8 = 6x^2 +14x + 8
The tallest man had a more extreme height because he was over 10 standard deviations away from the mean, whereas the shortest man was only around 8-9 standard deviations away from the mean
They way how you put it looks confusing sorry
