Since these are all n^2, you need to add/subtract the coefficients and keep the n^2.
6 - 5 + 7 = 8
8n^2
My best guess would be to take a side "s" and multiply it by the other side (which would also be s because of a squares properties). Your answer: s*s, or more simply, s^2.
<u>We are given:</u>
Time period: 3 days and 18 hours
Energy consumed in given time period: 5400 watt-hours
<u>Converting time to hours:</u>
We know that one day is 24 hours
So, 3 days = 72 hours
Time period = 3 days + 18 hours
Time period = 72 hours + 18 hours
Time period = 90 hours
Converting to days
Time period = 3.75 days
<u>Watt-hour consumption in a day:</u>
Consumption = 5400 watt-hours / 3.75 days
Consumption = 1440 watt-hours/day
Answer:
4 13/30
Step-by-step explanation:
1 3/5 + 2 5/6
= 8/5 + 17/6
= 48/30 + 85/30
= 133/30
= 4 13/30
I think the answer is A because they are not B because they are not all equal. They are not c because they are not suppose to be that close.
