Answer:
y² + 10y + 6x + 58 = 0
Step-by-step explanation:
Focus of the parabola has been given as (-7, -5) and directrix as x = -4
Let a point on the parabola is (x, y).
By the definition of a parabola, "distance of a point on parabola is equidistant from focus and directrix".
Distance from focus of the given point = 
Distance of the point from directrix = 
Therefore, equation of the parabola will be,


x² + 14x + 49 + y² + 10y + 25 = x² + 8x + 16
y² + 14x + 10y + 74 = 8x + 16
y² + 10y + 6x + 58 = 0
3(13-2a)=-3+a
39-6a=-3+a
42=7a
a=6
A (it’s a slight increase)
if you have a TI-84 calculator you could solve this problem in seconds.
Answer:
24
Step-by-step explanation:
3 times 4 times 2
3 times 4 is 12
12 times 2 is 24
