the formula for perimeter is l+l+w+w
So 9+9+6+6= 30 meters of fence
-9 is the answer to this equation
<span> The coordinates of the focus are </span><span><span>(<span>h,k+<span>1/<span>4a</span></span></span>)</span><span>(<span>h,k+<span>1/<span>4a</span></span></span>)
y=1/38*x^2
here h=0,k=0 ,a=1/38
so if we put values to find focus
focus(0,0+1/4*1/38)=(0,9.5)
</span></span><span>
</span>
The value exponential is 18
Is answer 21?
i assumed number as x
then i followed the process
