Question

Suppose B is between A and C. If AB = 7 and AC = 11, find BC.

A
7
С
B.
11
BC = 4
BC = 18
BC = 7
BC = 12

Answer 1

answer is BC=4

notice that the starting point is A and the endpoint is C, it stated that from A to B the value is 7 and from A to C the value is 11 we just need to subtract AC-AB to find the third value of it

AC-AB= 11-7 =4
