Answer:
Tim is 48
Step-by-step explanation:
13 x 3 = 39
39 + 9 = 48
If Tim is 3 times the age of John you multiply John's age (13) by 3 and add 9 to the sum because Tim is 9 years older.
48
3 times 13 (john's age) = 39
39 + 9 = 48 (nine years older than 3 times (39) so you add 9)
Therefore, Tim is 48.

If it's just distribution, not solving for s (I mean I could but do you need to?):
5(2s² - 3s + 4) Distribute/multiply 5 into (2s² - 3s + 4)
(5)2s² - (5)3s + (5)4
10s² - 15s + 20
