Answer 2

To solve this problem, let's break down the given information:

MP: PN = 2:5

This ratio indicates that the length of segment MP is 2 units, and the length of segment PN is 5 units.

MP - MN = 12 cm

This equation implies that the difference between the lengths of segments MP and MN is 12 cm.

To find the length of segment MN, we need to determine the value of the unit length in the given ratio.

Let's assume the unit length is represented by 'x'.

According to the ratio MP:PN = 2:5, we can write the equation as:

MP/PN = 2/5

Substituting the lengths, we have:

2x/5x = 2/5

Cross-multiplying, we get:

5(2x) = 2(5x) 10x = 10x

This equation tells us that the value of 'x' cancels out, which means the value of 'x' could be anything.

However, we can still find the length of MN using the given difference between MP and MN.

MP - MN = 12 cm

Substituting the lengths, we have:

2x - MN = 12

To isolate MN, we can subtract 2x from both sides:

MN = 2x - 12

Since we don't have the specific value of 'x', we cannot determine the exact length of MN.
