Answer:
The answer will always be negative
Step-by-step explanation:
The rule is if you multiply positive by positive it will equal positive.
If you multiply negative and negative it will equal positive.
But if you multiply negative and positive it will equal negative.
First move the 14 over so 1/3s = 12 then do 12 divided by 1/3, that would be 36 so s=36
Answer:
The center is located at (-1, -2), and the radius is 5.
Step-by-step explanation:
The general equation of a circle is given as
(x - a)^2 + (y - b)^2 = r^2
where
a and b are the centre of the circle and r is the radius
Given the equation
x2 + 2x + y2 + 4y = 20
add 1 ad 4 to both sides
x2 + 2x + 1 + y2 + 4y + 4 = 20 + 4 + 1
factorise
(x +1)^2 + (y+2)^2 = 5^2
comparing with the general equation
a = -1, b = -2, r = 5 (all measured in units)
