Answer: A. -1
Step-by-step explanation:
(x - 2)2 + 5(x - 2) = -6
2x-4 + 5x -10= -6
Combine like terms
7x-14=-6
Add 14 to both sides
7x=8
Divide
X= 8/7 or 1.14 (rounded)
1.14 - 2= -0.86 which can be rounded to -1
All you do is 1x+2x+5x=8x then you turn 4 s into pints. 1 gallon equals 4 pints 4*4=16 pints. 8x=16 x=2. Then you multiply everything by 2
1*2=2
2*2=4
2*5=10

Step-by-step explanation:
The sample is not a representation of the population, the population of students in colleges are high thus at least 10% of the population should be surveyed, this gives a better representation of the entire population.
The survey will also be biased as she stands outside the engineering building only and other students not belongings to this faculty might not be able to participate, thus the responses she will get will tend towards the favourable direction for the engineering students and will not reflects the entire students including non engineering students opinions on their college class schedule.
4:50am
Because 6:20 plus 1/2 is 6:50 because 1/2 of an hour is 30 min then 6:50 plus 11 would 17:50-12=5.50am
