Dan's age is x.
Jack is three years older than Dan, so his age is x+3.
Harold is twice as old as Jack, so his age is 2(x+3).
Harold's age is five times Dan's age.

Jack is 5 years old.
Omggg hiii you divide both sides by 14 and your answer would be 6
Answer:
answer=30
Step-by-step explanation:
by taking the length as x
1 millimetre = 10 metres
3 millimetres = x
10×3= 30 metres
HOPE THIS HELPS
I think u would do 18+5.5
Then multiply that by 5
A = L * W
P = 2(L) + 2(W) or P = 2(L + W)
7 * 10 + 7 * 2 = 7(10 + 2) = 7 * 12.....this will get u the area
2 * 7 + 2 * 12 = 2(7 + 12) = 2(19)...this will get u the perimeter
7 + 12....this gets u neither
2(7 + 12).....this will get u perimeter
7 + 12 + 7 + 12......this will also get u perimeter
7 * 12....this will get u area
