Answer:
The answer is d.
Step-by-step explanation:
:)
We want to recast the equation into the standard form equation for a circle centered at (h, k) with radius r. That equation is
... (x -h)² + (y -k)² = r²
Start by completing the square for both x-terms and y-terms.
... x² - 4x + y² + 4y = k
To do that, add the squares of half the coefficients of the x- and y-terms.
... x² - 4x + (-2)² + y² + 4y + 2² = k + (-2)² + 2²
... (x -2)² + (y +2)² = k + 8 = r² . . . . . this is now equal to the square of the radius, so we have
... k + 8 = 6² = 36
Subtracting 8 gives
... k = 28 . . . . . . . matches selection D)

10, x = 10
x/5=2
simplify the equation to the form
x/5=2
Simplifying:
+ 0.2x=2
move all terms containing x to the left and all other terms to the right.
+ 0.2x=+2
simplify left and right side of the equation.
+ 0.2x=+2
divide both sides of the equation by 0.2 to get x.
x=10
Hope it helps.
