Answer:
Below in bold.
Step-by-step explanation:
x^2 + y^2 - 8x + 12y + 40 = 0
x^2 - 8x + y^2 + 12y = -40
Complete the square on the x and y terms:-
(x - 4)^2 - 16 + ( y + 6)^2 - 36 = -40
(x - 4)^2 + (y + 6)^2 = -40 + 16 + 36
(x - 4)^2 + (y + 6)^2 = 12
So the centre is at (4, -6) and the radius is √12.

Answer:
12 heads
Step-by-step explanation:
if each monster has 47 legs, then there cant be more then 2 monsters because that would be too many legs...and there cant be just 1 monster....because that would leave (106 - 47) = 59 legs....and human legs wont add up to 59....
2 monsters = (2 * 47) = 94 legs........leaving (106 - 94) = 12 legs
each human has 2 legs.......so that means 12/2 = 6 humans.
so we have 2 monsters (each with 47 legs) + 6 humans (each with 2 legs) = 106 legs
so we have 2 monsters and 6 humans....each monster has 3 heads..and if we have 2 monsters, we have (3 * 2) = 6 heads...and if we have 6 humans, we have 6 heads.....so there is a total of 12 heads <====
A.6
The formula is An=An-1+d
120/4 = 30
5 * 30 = 900
120 pens : 900 pencils
If there are 120 pens, there are 900 pencils.
