Answer:
(-7, 4) and 7
Step-by-step explanation:
The standard equation of a circle is expressed as (x - a)^2 + (y - b )^2 = r^2
Where the center is the point (a, b) and the radius is r
Note: simply inserting the variables and playing around with your signs gives you the value for (a and b)
The square root of the radius gives you the value for r

Answer:
-3 and -2
Step-by-step explanation:
7x² + 19x + 21 = 4x² + 4x + 3
combine like terms:
3x² + 15x + 18 = 0
3(x² + 5x + 6) = 0
(x + 3)(x + 2) = 0
x = -3
x = -2
Answer:
3 apples for 1.29
Step-by-step explanation:
