Answer:
xy = 72
2x + 2y = 34 (Im assuming uts a rectangle or square)
2 (72/y) + 2y = 34
144 + 2y^2 = 34y
2y^2 - 34y + 144 = 0
y = 9 or 8
So the length is 9 and width = 8
Step-by-step explanation:
By using x-method we got that factorization is (x+5)(x-5)
<h3>What is factorization ?</h3>
factorization is writing a expression as a product of several factors.
So Given polynomial is
Now we will factorise this using x method
Here a=1 b=0 and c= -25
so ac=-25
Now We will write -25 at the top.
and 0 at the bottom.
No we will find two numbers that multiply to the top number -25 and add to the bottom number 0. Hence those numbers are -5 and 5.
Now we can write equation as
By using x-method we got that factorization is (x+5)(x-5)

The y intercept is -4 and the 2/3x is the slope
Answer:
p = 0.68 and p^ = 0.6
Step-by-step explanation:
Jackie received 68% of the votes in an election.
Here p is the decimal equivalent of 68 %.Hence ,
p = 0.68
Now we have taken a sample of 30 people from the total number of voters and we have to find the percentage of votes that Jackie gets in this .
Out of 30 people Jackie got 18 votes. Hence,
p^ = = 0.6
Hence the values are
p = 0.68 and p^ = 0.6
In the random sample we have taken the probability of Jackie has decreased but it will be compensated by another sample where it will be more.
The answer is -4.
