the answer to this problem is (1,3)
First, lets find how many miles the cyclist can ride per minute (speed = distance/time).
18/45 = 0.4 miles per minutes
Second, lets find how many miles the cyclist can ride per hour.
0.4 * 60 = 24 miles per hour
Third, lets find how many miles teh cyclist can ride in 6 hours.
24 * 6 = 144 miles in 6 hours
Best of Luck!
Since I just realized that you meant x^2-2x+1, let me evaluate this step by step:
x^2-2x+1
((-3)^2)-(2(-3))+1
9-(-6)+1
9+6+1
16
Therefore, that would equal 16.
The correct answer is
(1,3) is the centroid
Enter (1,3) in the boxes
The one wall would be 13 feet long.
13+13+13+13= 52 feet.
