12 I think, because area = base times height, so if you work backwards and divide 84 by 7 it equals 12
Answer:
The answer is b
Step-by-step explanation:
Okay:
For line “l”: y=4
For line “m”: y=-2/1+4
For line “p”: x=-4
For line “n”: y=1x-1
<span> we have that
standard form of equation for parabola:
(x-h)^2=-4p(y-k)
(h,k) --------->being the (x,y) coordinates of the vertex.
Parabola opens downwards because focus is below vertex on the axis of symmetry.
For given problem:
</span><span>vertex: (-3,2)
axis of symmetry: x=-3
p=distance from vertex to focus on the axis of symmetry=2-(-1)=3
4p=12
Directrix: y=2+p=5
Equation:
(x+3)^2=-12(y-2)
the answer is </span>(x+3)^2=-12(y-2)
Answer:
The distance between the two points is 10.63015
D=10.63015
