I don't exactly know what you're asking but I can give you this:
Aiden paid 22.2 $ in total
His sister paid 8.5$ in total
He paid 13.7 $ more than his sister
Ok so assuming you don't get tired and the rate stays the same
rate=amountwork/timeitdonein
rate=800/15
euals
6000/time
800/15=6000/time
simlify for ease
160/3=6000/time
multiply both sides by 3time
160time=18000
divide both sides by 160
time=112.5
means 112.5 minutes or 1hour, 52 minutes, 30 seconds
A. 800/15=6000/t or
15/800=t/6000
B. solved, 112.5 minutes
Answer:
2(2n² + 2n) + 1
Step-by-step explanation:
(2n + 1)² can also written as
(2n + 1) × (2n + 1)
= 4n² + 2n + 2n + 1
= 4n² + 4n + 1
= 2(2n² + 2n) + 1
= an odd
Hence Proved!
