Answer:
(x-4)^2+(y-4)^2=25
Step-by-step explanation:
the standard equation of a circle is (x-h)^2+(y-k)^2=r^2 where (h,k) are the coordinates of the center and r is the radius. In your case, just plug your the numbers into the equation
15% of x = 21
Set up proportions.
15/100 = 21/x
Cross multiply the numbers (15 by x, 21 by 100).
Divide 2100 by 15x to get x.
2100/15 = 140
X is 140.
Answer:
3ac-a+2b
a=2,b=1,c=4
Step-by-step explanation:
3*2*4-2+2*1
24-2+2=24
44 because the absolute values are 131 and 87 and to find difference you subtract.
