Answer:
The standard form of the quadratic equation is x² + 3·x - 4 = 0
Step-by-step explanation:
The standard form of a quadratic equation is a·x² + b·x + c = 0
Given that the expression of the quadratic equation is (x + 4)·(x - 1) = y, we can write the given expression in standard form by expanding, and equating the result to zero as follows;
(x + 4)·(x - 1) = x² - x + 4·x - 4 = x² + 3·x - 4 = 0
The standard form of the quadratic equation is x² + 3·x - 4 = 0

Answer:
2,700
Step-by-step explanation:
2,700 fans would go in per hour you would have to divide the gates and 2 ticket booths and then with that you times 600 by the number you get by dividing
A=P(1+r/100)^n
A=500(1+4/400)^24
A=500(1.01)^24
A=634.87
The answer to your question is -16/3
