V=\underbrace{(x+4)(5x-4)}(2x-1)= \\  \\
= (5x^2+20x-4x-16)(2x-1) = (5x^2+16x -16)(2x-1)= \\  \\ 
10x^3+32x^2 -32x -5x^2-16x +16 =  \\  \\ 
=10x^3 +(32x^2-5x^2) +(-32x-16x) +16 =  \\  \\ 
= \boxed{\bold{10x^3 +27x^2 -48x+16}}

What are the factors of (r+t)(e)
mina [271]

Depending on the values of  'r',  't', and  'e', the numerical value of that expression
might have many factors. 

For example, if it happens that r=5, t=1, and e=4 for an instant, then, just
for a moment,  (r + t)(e) = (5+1)(4) = 24, and the factors of (r+t)(e) are
1,  2,  3,  4,  6,  8,  12, and  24 .   But that's only a temporary situation.

The only factors of (r+t)(e) that don't depend on the values of  'r',  't',  or  'e' ,
and are always good, are  (<em>r + t</em>)  and  (<em>e</em>) .

Tatiana [17]
<span>The equation is e = 300 - 10t. t is greater or equal than 0 and given that e cannot be negative, 300 - 10 t greaetr or equal than 0 => 10 t greater or equal than 300, and t greater or equal than 300/10 = 30. This is the viable points are times from 0 to 10 and elevation from 300 to 0. Some points are (0,300) which is the initial point (when Rory is on the top); (1, 290); (2, 280); (3, 270); (4, 260); (5, 250); (6, 240); (10, 200), (20, 100), (30, 0).</span>
