Răspuns :
a + a + 2 + a + 4 = 24
3a = 24 - 6
a = 18 : 3
a = 6
a + 2 = 6 + 2 = 8
a + 4 = 6 + 4 = 10
3a = 24 - 6
a = 18 : 3
a = 6
a + 2 = 6 + 2 = 8
a + 4 = 6 + 4 = 10
a |---|
b |---|+2|
c |---|+4| } 24
1 + 1 + 1 = 3 ( segmente egale )
24 - 2 - 4 = 18 ( suma celor 3 segmente egale )
18 : 3 = 6 ( a )
6 + 2 = 8 ( b )
6 + 4 = 10 ( c )
b |---|+2|
c |---|+4| } 24
1 + 1 + 1 = 3 ( segmente egale )
24 - 2 - 4 = 18 ( suma celor 3 segmente egale )
18 : 3 = 6 ( a )
6 + 2 = 8 ( b )
6 + 4 = 10 ( c )
