Step-by-step explanation:
It is been considered that Discriminant is calculated by the following formula:
D = b*b - 4 * a * c
In order to simplify the calculations we can divide all the numbers by 2 and we will have the same quadratic equation:
-x^2 -4x+4=0
and as usual quadratic equation is presented as the following:
ax^2 - bx + c = 0
so in our case a = -1; b = -4; c = 4;
Then D = -4*4 -4*(-1) * 4 = -16+16 = 0
I am not quite understanding the following phrase:
"and what does it value mean about the number about the number"
but if the question was in regards of the following number '-2x^2' so number ^2 is actually the value of power so 'x' is multiplied on it is own and this equation basically means the following:
-2x^2 = -2 * (x) * (x)
The null hypothesis suggests that there is no statistical difference when a study of observations is made.In other words, there is no statistical difference between two variables such that when one variable is adjusted it has no significant difference on the other whatsoever.
Answer:
It is D.

Hi there,
Recall how each bracelet sells for 6 dollars.
Hence, the expression for selling b bracelets is 6b, where b is the number of bracelets sold for the price of 6 dollars.
Profit is the actual amount of money that is earned after you subtract expenses from the total sales.
For instance, if you make $100 from selling items, and you spent $25 on your supplies, then your profit is .
In this case, you need to subtract the $28 spent on supplies from the amount of money that you have made, which is the expression 6b.
Hence, the expression for the profit is:
Hope that helps.
