sandbox 1 area = 5*5 = 25 square m
sandbox 2
25=w*(3w+1)=
3w^2+w-25=0
w=2.7248 (round to 2.72 m)
2.72*3=8.16+1 = 9.16
Longest side = 9.16 meters
The answer is:

But if x2 was supposed to be x^2 then the answer is:
<span>What is r = wp, for p
</span>r = wp...divide both sides by w
so then p = r/w
Given :
Time they traveled in a day ,
.
Average speed ,
.
To Find :
How far did they hike altogether in 4 days .
Solution :
We know , distance covered is given by :

So , distance covered in 4 days is :

Therefore , distance they hike in 4 days is 38.5 miles .
Hence , this is the required solution .
1 is : d>-9
2 is: k ≥ -18
3 is: g>-1
4 is: n<-40
5 is: w ≤3
That should be correct.
