5 divided by 4=1.25 I think I am right
Area of a quarter circle = 1/4 * pi * r^2
= 1/4 * pi * 4^2 = 12.6 m to 3 sig figs.
perimeter = 4 + 4 + 1/4 * 2 pi * 4 = 14.3 to 3 sig figs.
Given that i<span>f
there are x teams in a league and each team plays every other team
twice, then the total number of games (n) to be played is given by

If </span><span>a chess league has 15 teams the total number of games to be played if each team plays every other team twice is given by

Least common denominator is (x-1)(x-2) = x²-3x+2.
2x(x-2)/((x-1)(x-2)) - (2x-5)/((x-1)(x-2)) = -3(x-1)/((x-1)(x-2))
2x(x-2) - (2x-5) = -3(x-1)
(2x²-4)-(2x-5) = -3x+1
2x²-2x+1 = -3x+1
2x²+x = 0
x(2x+1) = 0
x = 0,-½
If "x" is a multiplication sign:
-3 * 98 + 193 =
-294 + 193 =
101
