3
Answer:
2
Step-by-step explanation:
2/3÷1/3
Changing the divide sign into multiply will invert the term after it
So we get
(2/3)*3
(2*3)/3
We get
2

Answer:
The number of ways is 6435
Step-by-step explanation:
Given
Required
Number of ways a group of 8 can be formed
Here, I'll assume each category of people are distinct:
Hence;
Number of ways is then calculated as follows:
Where
So, we have:
<em>Hence, the number of ways is 6435</em>
Answer:
A is correct
Step-by-step explanation:
What we need to do here is to multiply all the roots together
The roots are;
3, √5 and -√5
Let’s have them in form of a sum
if x = 3, then the root is x-3
If x = √5, then the root is x-√5
If x = -√5, then the root is x+ √5
Now we need to multiply all these together to arrive at the original polynomial
Let’s start by using the roots
(x-√5)(x+ √5)
we can use the difference of 2 squares here and we arrive at (x^2 -5)
So finally, the polynomial would be;
(x^2-5)(x-3)
= x(x^2-5) -3(x^2-5)
= x^3-5x-3x^2+15
By rearranging, we have;
x^3-3x^2-5x+15
