Answer: 3.5, 4.5, 9.5, 3.5
Step-by-step explanation:
Look at the image below to see where A, B, C, and D are.
A + B = 8
B + D = 8
A + C = 13
C - D = 6
we can see that A + B = 8 and D + B = 8, so A = D
substitute this into A + C = 13 to get D + C = 13
from D + C = 13 we can get D = 13 - C
plug this into C - D = 6 to get C - (13 - C) = 6
2C - 13 = 6
2C = 19
C = 9.5
Now we can find D = 13 - C = 13 - 9.5 = 3.5
D = 3.5
Now we can find A = D = 3.5
A = 3.5
Now we can find B from A + B = 8
B = 8 - A = 8 - 4.5 = 4.5
B = 4.5
The polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3 is 
Step-by-step explanation:
We need to find a polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3.
If -1, 1 and 3 are real zeros, it can be written as:
x= -1, x= 1, and x = 3
or x+1=0, x-1=0 and x-3=0
Finding polynomial by multiply these factors:

So, The polynomial function whose real zeros are in -1, 1, 3 and whose degree is 3 is

144
Step-by-step explanation:
The reduced form of
32
48
is
2
3
Steps to simplifying fractions
Find the GCD (or HCF) of numerator and denominator
GCD of 32 and 48 is 16
Divide both the numerator and denominator by the GCD
32 ÷ 16
48 ÷ 16
Reduced fraction: 2/3
This can be solved using permutations.You can get more into this online or just accept a quick answer here.
Since there are certain roles to be filled this is a permutation.
You need a somewhat smart calculator for this.
If I remember this right you'd type in the number of people you are choosing from, P , and then the places you are trying to fill.
So it should look like this:
13 P 5
You can find where permutations and combinations are in your calculator using a handbook or the internet but usually it looks like nPr for permutation or nCr for combination.
