Answer:
306 km
Step-by-step explanation:
put both of them to equal in ratio form so now
85 / (7/6) = x / (21/5)
85 * (21/5) = 7/6x
357 = 7/6x
x = 306 km
. 66 the 6 keeps going on and on so you can just write. 66 with a line over the second 6.
The given function, f(x) = -3, written as a simplified polynomial is 2x² - 6x- 3 = 0
<h3>Simplified Polynomials</h3>
From the question, we are to determine f(x) = -3 as a simplified polynomial
From the given information, we have that
f(x) = -2x^2 + 6x
Rewrite the the given equation properly.
Rewriting, we get
f(x) = -2x² + 6x
Also, from the given information
We have that
f(x) = -3
Thus, we can write that
- 3 = -2x² + 6x
Writing the above equation as a simplified polynomial, we get
- 3 = -2x² + 6x
2x² - 6x- 3 = 0
Hence, the given function, f(x) = -3, written as a simplified polynomial is 2x² - 6x- 3 = 0
