A + E + N = 122
E = 2N
A = 7 + E....A = 7 + 2N
(7 + 2N) + 2N + N = 122
5N + 7 = 122
5N = 122 - 7
5N = 115
N = 115/5
N = 23 <== North America
E = 2N
E = 2(23)
E = 46 <== Europe
A = 7 + E
A = 7 + 46
A = 53 <=== Africa
we know that
If the only factors a polynomial are
and itself, then that polynomial is prime.
so
If the polynomial has at least one root (one x-intercept) then the polynomial is not prime
Using a graph tool
<u>case 1) </u>

see the attached figure N 1
The polynomial has one root-------> the polynomial is not prime
<u>case 2) </u>

see the attached figure N 2
The polynomial has three roots-------> the polynomial is not prime
<u>case 3) </u>


see the attached figure N 3
The polynomial has zero roots-------> the polynomial is prime
<u>case 4)</u>


see the attached figure N 4
The polynomial has two roots-------> the polynomial is not prime
therefore
<u>the answer is</u>
------> is prime
Answer:
-4/9
Step-by-step explanation:
5*8 = 40
6*15 = 90
You keep the negative and add it to the final product which is -40/90.
Decimal is: -0.444444444444444444444444444444444444444444444444444444444444444
