Answer:
The answer to your question is:
Step-by-step explanation:
Data
x² + 8x = -4y - 8
x² + 8x + 16 = -4y - 8 + 16
x² + 8x + 16 = -4y + 8
(x + 4)² = -4(y - 2)
(x + 4)² = 4(-1)(y - 2)
Vertex = (-4, 2)
p = 1
Focus = (-4, 1)
Axis of symmetry x = -4
Directrix y = 3
Hmmm show me what u know and then i can tell u the right answer that u are looking for
Convert the meter distance to KM so thaey are all the same measurement:
1 meter = 0.001 km
400 m x 0.001 m/km = 0.4 km
Now add all three distances:
Total distance = 0.4 + 40.1 + 12.2 = 52.7 km.
The answer is B.

So the perimeter(P) of a rectangle would be:
P= 2L+2W
L being the length and W being the width.
The problem says the length is 4cm more than the width, so L= 4+W.
So if we substitute L with 4+W, we get:
P= 2(4+W) + 2W
Use the Distributive Property
P= 8+2W+2W
Combine like terms
P=8+4W
Since we're given the perimeter, we could replace P with 52. So:
52=8+4W
Subtract 8 to both sides
44=4W
Divide 4 to both sides
11=W
Therefore, the width is 11cm
And since the length is 4cm more than the width, we could add 4cm to 11cm to find that the length is 15cm
Thus, the dimensions of the rectangle are 15cm by 11cm
