X+y+z=51
y=2z
z=9+x
subsitute those
x+2z+9+x=51
x+2(9+x)+9+x=51
x+18+2x+9+x=51
4x+27=51
minus 27 both sides
4x=24
divide by 4
x=6
sub back
z=9+x
z=9+6
z=15
y=2z
y=2(15)
y=30
the numbers are
6,30,15
1 cm is regular
but 1 cm 2
means that you multiply 1 by 1 which is 1
for example if you have 15cm 2 you would multiply 15 by 15 and get 225
and 15 cm 3 would be 15*15*15 and you would get 3375
