Answer: Choice C) 
This is the same as saying 
=============================================================
Explanation:
First get everything to one side
x^2 + 13 = 8x + 37
x^2 + 13 - 8x - 37 = 0
x^2 - 8x - 24 = 0
Here we have a quadratic in the form ax^2+bx+c = 0
Note how a = 1, b = -8, c = -24
Those values are plugged into the quadratic formula below

This shows the answer is choice C.
The plus minus breaks down that equation these two solutions

<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:
About 20%
Step-by-step explanation:
The probability of a point on the un-shaded region will be given by;
Area of the shaded region/total area
Considering that the circles are of the same size, then the length of the square is 2d
Area of the square = 4d²
Area of the shaded = (4d² -4π(d/2)²
= 4d² -πd², but π = 22/7
= 6/7d²
Probability = (6/7d² ÷ 4d²) × 100%
= (6/28 d²) × 100%
= 21.42 %
Therefore; the answer is about 20%
