(x-2)^2+20=0
(x-2)^2=-20
If you root both sides you will yield complex numbers (i, imaginary unit is such that i^2=-1),
x-2=20i
x=2+20i
and whenever x is a solution a complex conjugate x* is also a solution,
x*=2-20i
So the answer is A.

Lets say Ben and Jerry sold 'x' number of shakes.
If they have sold 'x' number of shakes then they must have sold number of cones.
Now, each ice cream cone costs $2.00 and each shake costs $9.00.
Last month the total sale totaled $3,900.00
Now,
The equation to represent the relation between the total sales and number of ice cream cons, number of shakes sold is given by:
Solving for 'x' we get:
We had assumed that 'x' number of shakes were sold, therefore we know that 300 shakes were sold and numbers of cones were sold which means ice cream cones were sold.
So, 600 ice cream cones were sold and 300 shakes were sold last month.
60 /1 = 120 /2 = 180 /3

Convert 8m to cm.
1 m = 100 cm
Multiply:
8 * 100 = 800
So 8 m is equal to 800 cm.
Both of them are equal, so 800 cm is not bigger than 8 m.
