Answer:  The required value of c is 5.

Step-by-step explanation:  We are given to Alessandro wrote the following quadratic equation in standard form.

We are to find the value of c in his new equation.

We know that

a quadratic equation can be written in standard form as follows :

ax^2+bx+c=0,~a\neq 0~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

So, the given equation can be written as :

-6=x^2+4x-1\\\\\Rightarrow x^2+4x-1+6=0\\\\\Rightarrow x^2+4x+5=0.

Comparing with the standard form (i), we find that the value of c is 5.

That is, c = 5.

Thus, the required value of c is 5.

Convert 12080 gallons per month into liters per hour
Anastaziya [24]

In this question , we have to convert 12080 gallons per month to liters per hour .

There are 3.78541 liters in 1 gallons , and there are 30 days in a month, and 24 hours in a day .

So to convert 12080 gallons per month, we have to multiply 12080 by 3.78541 and divide the result by the product of 30 and 24. THat is

12080 gallons per month = \frac{12080*3.78541}{24*30} liters / hour

= \frac{45727.75280}{720} liters/ hour = 63.51 liters/hour
