The regression equation of the data values is y = 0.3x^2 - 2.8x +4.2
<h3>How to determine the regression equation?</h3>
Using a technology such as a graphing calculator, we simply input the data values in the graphing calculator and then wait for the result.
The x coordinates must be entered into the x values and the y coordinates must be entered into the y values

Answer:
(C - B)/A = x
Step-by-step explanation:
Ax + B = C
-B -B
Ax = C - B
Divide both sides by A
x = (C - B)/A
(C - B)/A = x
In order: 6, 6, 12
1st: l x w | 3 * 2
2nd: 1/2(l x w) | 1/2(12)
3rd: 1st + 2nd | 12
Since it is 10 less and you are trying to find out your number, you add 10.
71+10= 81
So, your number is 81.
