Answer:
<em>12 </em>
<em> + 28 </em>
<em> - 60 r³ + 28 r² </em>
Step-by-step explanation:
a(b ± c) = ab ± ac (distributive property)

2r²(6r³ + 14r² - 30r + 14) = <em>12 </em>
<em> + 28 </em>
<em> - 60 r³ + 28 r²</em>
Well all you have to do is subtract 19,496 from 39,835. 39,835-19,496=20340 now you have to round to the nearest hundred. Your answer would be 20,300 miles
Answer:
13 does not equal -4, can I get more information please
In this question, it is given that y varies inversely as x . So the equation is

And here k is the proportionality constant .
And when x=6, y=12

So the values of the proportionality constant k is 72 and the correct option is B.
Plug in F(x) to the equation answer and see if it is true or false by plugging it in
