2(x^2+6x+9) = 2(x+3)^2
So after divided by (x+3), answer will be:
2(x+3)

For the regression equation and e the number of kilowatt-hours, in thousands, for a six-room house is mathematically given as
Y = 1.33-0.667X and 5.3332
<h3>What is the number of kilowatt-hours, in thousands, for a six-room house?</h3>
Generally, the equation for the standard deviation is mathematically given as
ₓ =
= 
= 2.72
= 
= 2.01
therefore correlation coff
r = 
r = 0.9038
In conclusion the regression equation is given
b = r_sy/sx
b = (0.9038)(2.01/2.72)
= 0.667
intercept
a = 7.4-0.667(9.1)
a = 1.33
The regression equation is
Y = 1.33-0.667X
(b) number of kilowatts x = 6 house
Y = 1.33-0.667X
Y = 1.33-0.667(6)
= 5.3332

Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
x = 1
Answer:
20 years
Step-by-step explanation:
Using the formula; A = P(1 + r)^t
We can plug in the known to find t
400 = 220(1.03)^t
then solve for t;
1.818 = 1.03^t
Introducing In
In 1.818 = t × In (1.03)
t = 20.225
t = 20 years to the nearest year
