First you'll take 18/2 which equals 9. Then 30/2 which equals 15. Then you can divide both 9 and 15 by 3. So 9/3 equals 3 and 15/3 equals 5. So the answer is 3:5.

2) 1/2
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
This is the equation for a circle which without numbers looks like (x – h)^2 + (y – k)^2 = r^2
This means that the radius is the square root of what ever number the equation is equal to. Since in this case it is 4 the square root of 4 is 2
The center of the circle is baced off h and k. In order to find where each one of them go, you would do the opposit of the number that is with them. With this equation the opposit of 4 is -4 so it will go -4 in the x direction and the opposit of -7 is 7 so it would go 7 in the y direction
Radius: 2
Center: (-4,7)
