I think your answer would be 14 if this is what it’s asking for
Because 6/6 makes 1 so 13+1 is 14
B) 4Na + O₂ → 2Na₂O
b) H₂ + Cl₂ ---> 2HCi
$1,365 is the answer, (the third choice)
The standard equation of a circle is
(x-h)^2 + (y-k)^2 = r^2
where the center is at point (h,k)
From the statement of the problem, it is already established that h = 2 and k = -5. What we have to determine is the value of r. This could be calculated by calculating the distance between the center and point (-2,10). The formula would be
r = square root [(x1-x2)^2 + (y1-y2)^2)]
r = square root [(2--2)^2 + (-5-10)^2)]
r = square root (241)
r^2 = 241
Thus, the equation of the circle is
