The perimeter of the square is given by:

Where,
x: square side.
Substituting values we have:

Rewriting the perimeter of the square we have:

Finally, dividing both values:

Answer:
the perimeter of the square is:

Answer:

Step-by-step explanation:
We have been given a graph of similar triangles. We are asked to find the value of x.
Since we know that corresponding sides of similar triangles are always in same proportion, so we will use proportions to find the length of x.

Upon cross multiplying our equation we will get,
Upon distributing 4 we will get,

Let us subtract 12 from both sides of our equation.

Upon dividing both sides of our equation by 4 we will get,
Therefore, the value of x will be 12.

Answer:
65 mph on level road
Step-by-step explanation:
Set b as average speed on the level road and (b-20) = average speed on the winding road
Distance = speed * time
Level Road distance + winding road dististance = 285 miles
Substituting b and (b-20), we have,
3b + 2(b-20) = 285
3b + 2b - 40 = 285
5b = 285 + 40
5b = 325
b= 325/5
b = 65 mph on level road
