If the equation of a circle is (x+5)^2 + (y-7)^2=36, its center point is
1 answer:
Answer:
centre = (- 5, 7 )
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + 5)² + (y - 7)² = 36 ← is in standard form
with h = - 5 and k = 7
centre = (- 5, 7)

Step-by-step explanation:
(3x2 - 2x - 4) (2x2 + x - 3)
6x4 + 3x3 - 9x2 - 4x3 - 2x2 + 6x - 8x2 - 4x + 12
Solving like terms
6x4 - x3 - 19x2 + 2x + 12
Answer:
a) area = side²
