Answer:
Option C.
Step-by-step explanation:
The lowest possible product would be -6724 given the numbers 82 and -82.
We can find this by setting the first number as x + 164. The other number would have to be simply x since it has to have a 164 difference.
Next we'll multiply the numbers together.
x(x+164)
x^2 + 164x
Now we want to minimize this as much as possible, so we'll find the vertex of this quadratic graph. You can do this by finding the x value as -b/2a, where b is the number attached to x and a is the number attached to x^2
-b/2a = -164/2(1) = -164/2 = -82
So we know one of the values is -82. We can plug that into the equation to find the second.
x + 164
-82 + 164
82
Answer: 11 girls were not selected.
Step-by-step explanation:
First let's find out how many girls their were in total. In this case their are 23.
Let's subtract 12 from 23. That ends up to be 11. (<em>subtract 23 from 11 / 11 from 23)</em>
-23
-12
