The <em><u>correct answer</u></em> is:

Explanation:
The Quadratic Formula is
,
where a, b and c are the coefficients of a quadratic equation written in standard form, or 0=ax²+bx+c.
This means that first, we need to make our equation equal 0.
We have
-2 = -x + x² - 4
To make this equal 0, we must cancel the -2. We do this by adding 2:
-2+2 = -x + x² - 4 + 2
0 = -x + x² - 2
Now we write this in standard form. This means the x² term must come first, then the x term, then the constant:
0 = x²-x-2
This makes a = 1, b = -1 and c = -2. We then plug this into the quadratic formula.

my answer is 100 % correct
Idk sry I wish I did know but I don’t
Answer:
d = r * t
r = 50 mph
this will be very easy.
d = r * t
r = 50 mph
t = 5 hours
d = 250 miles
In five hours at a constant speed of 50 miles per hour, you would have traveled 250 miles.t = 5 hours
d = 250 miles
In five hours at a constant speed of 50 miles per hour, you would have traveled 250 miles.
