Point M is marked on the segment AB. Find the length AB if AM = 40 cm, and the segment MB is shorter than the segment AM by m cm. Simplify the expression and its meaning when m = 14
Point M is marked on the segment AB. AM = 40 cm, and the MВ segment is shorter than the AM segment by m cm.
Suppose that the segment MВ has a length that is 40 – m.
Hence, the segment AB = AM + MB.
AB = 40 + (40 – m).
AB = 40 + 40 – m.
AB = 80 – m.
If m is 14, then the length of AB will be:
AB = 80 – 14 = 66 cm.
