Given:
The side of a square a, s+3.
The perimeter of a square is the sum of the four sides of the square. Hence,

I think the answer might be 72
Average speed of cyclist = x
average speed of car = 3x
x = 225/5
x = 45km/h
3x = 3(45)
3x = 135km/h
average speed of cyclist = 45km/h
average speed of car = 135km/h
The volumes will be the same, because the heights are equal and the cross-sectional areas at every level parallel to the bases are also equal.
The answer is C) 0
Because math
