Let the three integers be x - 1 x and x + 1
(x - 1)(x + 1) = 6x + 6
x^2 - 1 = 6x + 6
x^2 - 6x - 7 = 0
(x - 7)(x + 1) = 0
x - 7 = 0
x = 7
x + 1 = 0
x = - 1
the solutions are (7,0) and (-1,0)

Step-by-step explanation:
Lets Price of article is 100
Dep value after 1 year =100−
100
100×10
= 90
Dep. value after 2 year =90−
100
90×10
=81
Dep. value after 3 years =81−
100
81×15
=68.85
Total Dep. =100−68.85 = 31.15%
Area = x ( 2x+3)
as area is product of length and breath
Answer:
62.6%
Step-by-step explanation:
To convert the mountain height to miles, we divide its height in feet by the number of feet per mile. We want the fraction of that represented by 3 miles, so ...
(3 mi)/((25,289 ft)/(5,280 ft/mi)) × 100%
= 3(5280)/25289 × 100% ≈ 62.6%
If you climbed 62.6% of the mountain's height, you would be 3 miles above sea level.
