Answer:

3x + 10cm

Step-by-step explanation:

This is calculated as:

Length of Tom's pencil - Length is Ellen's pencil

Length of Tom's pencil: 5x+25cm long.

Length of Ellen's pencil : 2x+15cm long.

(5x + 25)cm - (2x + 15)cm

5x + 25 - 2x - 15

5x - 2x + 25 - 15

3x + 10 cm

Therefore, Tom's pencil is 3x + 10cm longer is than Ellen's.
