12. 123,067/10,000 = 12.3067
hope it helps</span>


Cancel out the denominators.
(x+5)² + 18 = -30
(x+5)² = -30 - 18
(x+5)² = -48
The equation is impossible, we have a negative number.
There isn't a number that squared gives a negative number (the square is always positive).
√(x+5)² = +/- √-48
x+5 = +/- √-48
IMPOSSIBLE
You can write the result in imaginary numbers
x+5=+/- 4i√3

Answer:
The number of units sold increased by 
Step-by-step explanation:
Vacuum dealer sold units in 2011 = 420
Vacuum dealer sold units in 2012 = 467
We need to find percent increase or decrease
Since, In 2012 units sold are greater than 2011, so there will be percent increase.
The formula used is: 
We have New Value (Units sold in 2012) = 467
Original Value (Units sold in 2011) = 420
Percent increase is:

So, The number of units sold increased by 
Should be 11.25 because 15 is 1/4 of 60 . U take 1/4 away from 60 so u gotta take 1/4 away from 15 which is 3.75 . And you get 11.25
