We divide by 2 on both sides.
We get the final answer as
x = 5/2 = 2.5
Answer:
21+10.5 which would equal 31.5
Step-by-step explanation:
40.2 - 13.7 = 26.5
26.5 / 13.7 * 100 = 193.43
answer
193%
Answer:

Step-by-step explanation:
I will begin with part two, first.
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.
Given
x² - 18x + y² - 10y = - 6
Using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(- 9)x + 81 + y² + 2(- 5)y + 25 = - 6 + 81 + 25, that is
(x - 9)² + (y - 5)² = 100 ← in standard form
with centre = (9, 5 ) and r =
= 10
