Ответ:
30
So the two sectors add to the full length:
JK + IJ = IK
x+6 + 9 = 2x
Rearrange:
x=15
So the numerical length:
2x
2*15
30
Ответ:
This is because JK + IJ = IK so x+6+9=2x
This can be simplified to x+15=2x and then even further to 15=x
Now that you have x, you can plug it into the equation for JK
so 15+6=21
