Two circles are concentric if they have the same center. Which equation represents a circle that is concentric with the circle shown but has a radius that is twice as large? (x – 4)2 + (y – 6)2 = 4 (x – 4)2 + (y – 6)2 = 16 (x – 6)2 + (y – 4)2 = 16 (x – 6)2 + (y – 4)2 = 4
Answers
From that, you choose that whose center is the same of your circle and the radius is the double.
The canonic equation of a circle is:
(x - a)² + (y - b)² = r²
Where a and b are the coordinates of the center (a,b) and r is the radius.
So, let's determine the center and the radius of all the equations given:
A) (x – 4)² + (y – 6)² = 4
Center (4,6),;radius = √4 = 2
B) (x – 4)² + (y – 6)² = 16
Center (4, 6); radius = √16 = 4
C) (x – 6)² + (y – 4)² = 16
Center = (6, 4); radius = √16 = 4
D) (x – 6)² + (y – 4)² = 4
Center (6, 4); radius = √4 = 2

Final answer:
The number that when divided by 12 equals 72 is 864. This is found by multiplying the divisor (12) with the desired quotient (72). Therefore, the answer is 864.
Explanation:
To solve for the number that when divided by 12 gives an answer of 72, we need to leverage the standard division operation in mathematics.
To find this number, we simply multiply 12 (the divisor) by 72 (the quotient). This is the reverse of the division process, also known as multiplication.
When we perform this calculation, 12 multiplied by 72, we find the answer to be 864. Therefore, 864 is the number that when divided by 12 gives you 72.

x=-3
Step-by-step explanation:
12-3x=-6x
12=-3x-6x
12= -9x
----------
-9. -9
12/9= -3
How I did it :
12 - 3x = -6x
Add 3 x to both sides:
12 = -3x
Then divide both sides by -3:
-4 = x

Answer:
The total area of the field is 343 square feet
Step-by-step explanation:
Let us solve the question
∵ There are 7 workers hired to seed a field by hand
∵ Each is given a plot 7 x 7 feet in size
→ The plot has shaped a square because its two dimensions equal
∴ The side of the plot =7 feet
∵ The area of the square = side × side
∴ The area of each plot = 7 × 7
∴ The area of each plot = 49 square feet
→ To find the total area multiply the area of 1 plot by the number
of the workers
∵ The total area = 49 × 7
∴ The total area = 343 square feet
∴ The total area of the field is 343 square feet
