We know that
<span>[average speed]=distance/time
distance=59+70-----> 129 km
time=4+5----> 9 hours
</span>
[average speed]=129/9----------> 14.33 km/hour
the first digit law
hope this helps
This is a true statement. Here's how we know. The factors of that general formula are (ax - b)(ax - b). If that is in fact the general formula of the quadratic shown, then our a would be 2 and our b would be 3, since 2 times 2 is 4 which is the leading coefficient, and 3 times 3 is 9 which is the constant. Those factors, filled in accordingly, would be (2x - 3)(2x - 3). If we FOIL those out we should get back the quadratic in question. FOILing gives us
![4x^2-6x-6x+9](https://tex.z-dn.net/?f=%204x%5E2-6x-6x%2B9%20)
which of course simplifies to
![4x^2-12x+9](https://tex.z-dn.net/?f=%204x%5E2-12x%2B9%20)
