Answer:
I believe it is -123
Step-by-step explanation:
you have to replace all the x's with -4 so you would do the equation -6(-4)^2+8(-4)+5
-6(-4)^2 is -96
-96+8(-4) is -128
-128+5 is -123
X=10 I think I’m not sure
We need to find the quotient of the given division problem.
In order to find its quotient, we will use long division.
)
First of all, we put x in the quotient as 
goes into 
, x times.
So, we get:
)(x
Upon subtracting, we get:
We can see that goes into 
, -2 times, therefore, the next term in the quotient will be -2. This makes our quotient as (x-2).
Answer:
(a) 9 buildings
(b) 2^n -1
Step-by-step explanation:
The number of distinct non-empty subsets of b objects is 2^b -1. Since the subsets are distinct, each could represent a list of the buildings, from the set of b buildings, in which a student is taking courses.
(a) For 8 buildings, 2^8 -1 = 255 students could enroll. for 9 buildings, 2^9-1 = 511 students could enroll.
For 500 students, 9 buildings are required.
__
(b) The maximum number of students for n buildings is ...
2^n -1
