Answer:
The answer is 5.
Step-by-step explanation:
Total number of people noticed by author = 28
Total number of black haired people = 27
So, total number of non black haired people = 1
Also given that 6 people had whole row of seats to themselves.
Let x be the number of non black haired people who had a whole row to themselves.
Since there is only one person with non black hair and has a whole row to himself because it is mentioned that one person had a row to himself which is non black haired.
Looking at above information we can say that x = 1.
Now we can say that the number of black haired people who had a whole row to themselves = 6-x
or 
Hence, the answer is 5.
f(x) -g(x) = -3x-5 -(4x-2)
distribute
-3x-5 -4x+2
combine like terms
-7x-3
Answer:
-7x-3
Answer:
B
Step-by-step explanation:
We have to find which trinomial has:
1) two terms that are the perfect square of two numbers
2) a terms that is the double product of the two numbers
the first condition is satisfied by A and B, but only B satisfied the second., in fact the trinomial can be rewrite as: (2a-5)^2
Options C and D are traps because the square of a number can’t be negative
