The standard equation is 4p(x-h) = (y-k)^2 where |p| = focal distance |4p| = focal width.
<span>x=-1/8y^2
-8x=y^2
4*(-2)(x-0) =( y-0)^2
p = -2, h=0, k=0</span><span>
focal width = |4*(-2)| = 8
The answer to your question is that the length of the focal width is equal to 8.</span>

Answer:
48 meters
Step-by-step explanation:
3*4 = 12
5*4 = 20
4*4 = 16
These are the sizes when the triangle enlarges with a scale factor of 4.
To find perimeter, you add the sides together
12+20+16 = 48
The perimeter is 48 meters
The answer is -125. Get this by taking (-5)(-5)(-5)
