A = L * W
L = n
W = n + 8

A = n(n + 8)
A = n^2 + 8n <==

<span>It is D: n(n+4). I solved it by a long, but easy method. First, I made up the value of N, the width, and made it 3. I then added 4 to 3, which is 7. So the length is 7 and the width is 3. The area of this made up rectangle is 21. The only answer choice that has 21 as the area is D.</span>

Help! Algebra!!!
balandron [24]
Thet contradict each other, that's why both of them are incorrect.
<span>Suppose that a polynomial has four roots: s, t, u, and v. If the polynomial were evaluated at any of these values, it would have to be zero. Therefore, the polynomial can be written in this form. 

p(x)(x - s)(x - t)(x - u)(x - v), where p(x) is some non-zero polynomial 

This polynomial has a degree of at least 4. It therefore cannot be cubic. 

Now prove Kelsey correct. We have already proved that there can be no more than three roots. To prove that a cubic polynomial with three roots is possible, all we have to do is offer a single example of that. This one will do. 

(x - 1)(x - 2)(x - 3) 

This is a cubic polynomial with three roots, and four or more roots are not possible for a cubic polynomial. Kelsey is correct. 

Incidentally, if this is a roller coaster we are discussing, then a cubic polynomial is not such a good idea, either for a vertical curve or a horizontal curve. I hope this helps</span><span>

Answer:

Below.

Step-by-step explanation:

I'll do number 20, 21, 22 for you.

20.  It is ±1, ±2, ±4, ±8.

21.   Reflected over the x-axis and down 4.

22. Common ratio = 25/5 = 5.

23.  Imaginary roots occur in pairs so there is also a root -5i.

The answer is c.

19. Option (a).

This is a translation of 4 to the left ( due to the (x + 4).

Find two consecutive odd integers whose product is 899
UNO [17]

Answer:

Step-by-step explanation:

Let two consecutive odd numbers

x, x+2

According to condition

X(x+2) = 899

x2 +2x -899=0

X2 +31x -29x -899=0

x(x+31) -29(x+31)=0

(x+31)(x-29)=0

X=-31 or x =29

Now,

X=29

X+2= 29+2 = 31

Two consecutive odd numbers is 29 and 31
