Answer:
(x+3)²+(y-4)²=36.
Step-by-step explanation:
For this, we need to use the equation of a circle which is:
(x-h)²+(y-k)²= r²
Simply substitute the center values for 'h,k', and the radius for 'r'.
This will give you:
(x+3)²+(y-4)²=36.

Answer:
The expression which represent the length of the rectangle is x + 1
Step-by-step explanation:
Given as :
The Area of rectangle = x² - 6 x - 7 square meters
The width of the rectangle = w = x - 7 meters
Let The length of rectangle = L meters
Now, <u>According to question</u>
∵ Area of Rectangle = Length × width
or, x² - 6 x - 7 meters² = L meters × w meters
or, x² - 6 x - 7 = L × (x - 7)
or, x² - 7 x + x - 7 = L × (x - 7)
or, x (x - 7) + 1 (x - 7) = L × (x - 7)
or, (x - 7) (x + 1) = L × (x - 7)
∴ L = 
I,e L = x + 1
So, The length of rectangle = L = x + 1
Hence,The expression which represent the length of the rectangle is x + 1 Answer
Answer:
The fourth pair of statement is true.
9∈A, and 9∈B.
Step-by-step explanation:
Given that,
U={x| x is real number}
A={x| x∈ U and x+2>10}
B={x| x∈ U and 2x>10}
If 5∈ A, Then it will be satisfies x+2>10 , but 5+2<10.
Similarly, If 5∈ B, Then it will be satisfies 2x>10 , but 2.5=10.
So, 5∉A, and 5∉B.
If 6∈ A, Then it will be satisfies x+2>10 , but 6+2<10.
Similarly, If 6∈ B, Then it will be satisfies 2x>10 , and 2.6=12>10.
So, 6∉A, and 6∈B.
If 8∈ A, Then it will be satisfies x+2>10 , but 8+2=10.
Similarly, If 8∈ B, Then it will be satisfies 2x>10. 2.8=16>10.
So, 8∉A, and 8∈B.
If 9∈ A, Then it will be satisfies x+2>10 , but 9+2=11>10.
Similarly, If 9∈ B, Then it will be satisfies 2x>10. 2.9=18>10.
So, 9∈A, and 9∈B.
