Answer:
20, increased, Bianca
Step-by-step explanation:
First one:
He is shown to have travelled 20km in 1 hour, so that's 20km/h.
Second:
The gradient is how steep the curve is, the steeper the faster the person is travelling. Due to the fact Bianca's curve becomes steeper, it shows she is travelling faster. Therefore, her running speed increases.
Third:
Bianca's line hits 50km before Alberto, so therefore she finished first.

Answer:
The answer is 286.
Step-by-step explanation:
<u>13! can be rewritten</u> as 13*12*11*10!.
Since <u>10! is on the top and bottom of the fraction</u>, we can<em> eliminate them</em>. We are then left with 13*12*11/3!.
3! = 6. We can <u>eliminate the 6 from the denominator by diving the 12 by 6</u> in the numerator to get 13*11*2.
Finally, we can can evaluate the expression to get 286.
Nope. They are not equal.
