Which is different? Find "both" answers.​
zimovet [89]

Answer : The different is, find BC - AC and find AC + CB, find AB and find CA + BC are same.

Step-by-step explanation :

As see that, AB is a line segment in which point C is represented in between the line.

As we are given that:

AC = 3

CB = 7

So,

AC + CB = 3 + 7 = 10

Similarly,

CA + BC = 3 + 7 = 10

Similarly,

AB = AC + CB = 3 + 7 = 10

But,

BC - AC = 7 - 3 = 4

From this we conclude that, find AC + CB, find AB and find CA + BC are same things while find BC - AC is a different thing.

Hence, the different is, find BC - AC and find AC + CB, find AB and find CA + BC are same.
