Question

If AB = 9 and BC = 12 then what is AC?

Answer 1

Answer:

AC = 12 cm

Step-by-step explanation:

AB=9 centimeters, you figure out what times what is 9. in this case, it is 3 for A and B. Then you go to BC=12 and 3 for B and 4 for C making it 12 So AC would equal 3x4.

Answer 2

AC = 21

Assuming this is on a line segment AC would be the full length of the line segment that you are trying to find and point B would be splitting in between.
So if the distance between AB is 9 and the distance between BC is 12 then you just add them up the get the full length of AC which is 21
