Answer:
The answer to your question is the last option
Step-by-step explanation:
Quadratic equation
2 = - x + x² - 4
Order the equation from the highest power to the lowest power. Do not consider 2 because it is not consider in the options given.
x² - x - 4 = 0
Identify a, b and c
(1) x² -(1) x - 4 = 0
a = 1 b = -1 c = - 6
Substitution

Step-by-step explanation:

A total of
108*19 = 2052
pages will be printed. We suppose paper will be purchased in reams of 500 pages each, so
ceiling(2052/500) = ceiling(4.104) = 5
reams will be needed. The the cost will be
(5 reams)*($3.69/ream) = $18.45
The paper for the reports will cost $18.45.
You begin with moving all terms to the left side and set them equal to zero. Then you set each factor equal to zero and you should come out with p= 0,8
Since the discount is 30%, then the sale is = 100% - 30% = 70% of the cost
= 70% of 50
= (70/100) * 50
= 0.7 * 50 = 35
Therefore sale = $35
