Answer:
Option A
Step-by-step explanation:
Given:
Center of circle = (h,k)= (3,8)
Radius = r = 5
The standard form of equation of circle with center and radius is:

Therefore, the general form of the equation of circle given is:

Hence, option A is correct ..
Answer:
B
Step-by-step explanation:
4*60=240
240/13.7*25=437
x + x +2 + x + 4 = 120 ( I think you mean linear equation!)
3x = 114
x = 38
the numbers are 38, 40 and 42
A+B = 2X -2
A-B = 4X -8
Add the equations,
2A = 6X - 10
A = 3X - 5
Now, 3X - 5 + B = 2X - 2
B = 2X-3X - 2 + 5
B = 3 - X
Hope this helps!
