Possible rational zeros are:
Step-by-step explanation:
We need to list all possible zeroes of the function 
using rational zero theorem.
The rational zero theorem.
rational zero theorem states that zeros can be found by dividing the factors of constant term called p by the factors of the leading co-efficient called q i.e
p/q
In our given function
p = 7
q = 5
Factors of p (7) = ±1, ±7
Factors of q (5) = ±1, ±5
So, possible rational zeros are:

Angle B = 56.309932474020215
This is through using a trigonometry calculator I forgot how to set it up tbh.
Hope this helps ;)
For extra info Angle C = 33.690067525979785.
They add up to 90 which added with the right angle of 90 means the interior angles add to 180 meaning it is in fact correct because a triangle is always 180 inside.
Answer:
Step-by-step explanation:
Total amount of money to be shared among Neymar, Rohit Sharma and Nadal is $250
Neymar gets two parts. This means that Neymar gets 1/2 × total amount of money.
Neymar gets 1/2 × 250 = 125
The percentage will be amount that Neymar gets divided by the total amount and multiplied by 100. It becomes
125/250 × 100 = 50%
Rohit gets three parts. This means that Rohit gets 1/3 × total amount of money.
Rohit gets 1/3 × 250 = 83.33
The percentage will be amount that Rohit gets divided by the total amount and multiplied by 100. It becomes
83.33/250 × 100 = 33.33%
Nadal gets five parts. This means that Nadal gets 1/5 × total amount of money.
Nadal gets 1/5 × 250 = 50
The percentage will be amount that Nadal gets divided by the total amount and multiplied by 100. It becomes
50/250 × 100 = 20%
<h2>>>> Answer <<<</h2>
Let's check which polynomial is divisible by ( x - 1 ) using hit , trial and error method .
A ( x ) = 3x³ + 2x² - x
The word " divisible " itself says that " it is a factor "
Using factor theorem ;
Let;
=> x - 1 = 0
=> x = 1
Substitute the value of x in p ( x )
p ( 1 ) =
3 ( 1 )³ + 2 ( 1 )² - 1
3 ( 1 ) + 2 ( 1 ) - 1
3 + 2 - 1
5 - 1
4
This implies ;
A ( x ) is not divisible by ( x - 1 )
Similarly,
B ( x ) = 5x³ - 4x² - x
B ( 1 ) =
5 ( 1 )³ - 4 ( 1 )² - 1
5 ( 1 ) - 4 ( 1 ) - 1
5 - 4 - 1
5 - 5
0
This implies ;
B ( x ) is divisible by ( x - 1 )
Similarly,
C ( x ) = 2x³ - 3x² + 2x - 1
C ( 1 ) =
2 ( 1 )³ - 3 ( 1 )² + 2 ( 1 ) - 1
2 ( 1 ) - 3 ( 1 ) + 2 - 1
2 - 3 + 2 - 1
4 - 4
0
This implies ;
C ( x ) is divisible by ( x - 1 )
Similarly,
D ( x ) = x³ + 2x² + 3x + 2
D ( 1 ) =
( 1 )³ + 2 ( 1 )² + 3 ( 1 ) + 2
1 + 2 + 3 + 2
8
This implies ;
D ( x ) is not divisible by ( x - 1 )
<h2>Therefore ; </h2>
<h3>B ( x ) & C ( x ) are divisible by ( x - 1 ) </h3>
