Answer:
equation of the circle J with center K(-7,3) and radius 6 is=
x^2+y^2+14x-6y+22=0
Step by step explanation:
Equation of circle with given centre (h,k) and radius r is
(x-h)^2+(y-k)^2=r^2
Given centre are K(-7,3) and radius 6.
So equation of Circle=
(x- -7)^2+(y-3)^2=6^2
x^2+14x+49+y^2-6y+9=36
x^2+y^2+14x-6y+22=0 answer
Answer: x = 1 ± i
Step-by-step explanation:
Solving the quadratic equation using the quadratic formula:
x = 
or 
From the question :
a = 1
b = -2
c = 2
substituting inside the formula
X = 
or
x = 
or 
x = 
or 
Recall ; 
can be written as 
X 
, and = i
Substituting this
x = 
or 
simplifying, we have
x = 1 + i or 1 - i
Let the length of the playground be x, then the width is 6 + x.
Area = length * width = x * (6 + x) = 6x + x^2 = 216
Solving the quadratic equation x^2 + 6x - 216 = 0, we have x = 12 or -18
i.e length = 12 and width = 6 + 18 = 18
