You basically solve 7!, which is 7*6*5*4*3*2*1= 5040 possible patterns.
I believe you meant: Use completing the square to determine the center and radius of the circle represented by this equation: <span>X^2+y^2-10x+6y=15
x^2 - 10x + 25 - 25 + y^2 + 6y + 9 - 9 = 15
Then:
(x-5)^2 + (y+3)^2 = 24 = 2sqrt(6)
This circle is centered at (5,-3) and has radius 2sqrt(6).</span>
Step by step explanation:
X + y=25
-y. -y
X=25-y
3x +4y= 90
3(25-y) =90
75-3y=90
-75. -75
-3y =15
/-3. /-3
Y=-5
X=25-(-5)
X= 25+5
X=30
The answer of the above diagram is A.
hope it helps☺
900 kilometres that’s the answer
