Simplify the rational expression. state any restrictions on the variable. n^4-11n^2+30/n^4-7n^2+10

Andrej [43]

<span>For this case we have the following expression:
</span> $\frac{n ^ 4-11n ^ 2 + 30}{ n ^ 4-7n ^ 2 + 10} 

$
<span> We are going to make the following change of variables:
</span> $x = n ^ 2
$
<span>Rewriting the expression we have:
</span> $\frac{(x ^ 2-11x + 30)}{(x ^ 2-7x + 10)} 

$
<span>Factoring the expression we have:
</span> $\frac{(x-5) (x-6)}{(x-5) (x-6)} 
$
<span>Canceling similar terms we have:
</span> $\frac{x-6}{x-2} 
$
<span>Returning the change we have:
</span> $\frac{n ^ 2-6}{n ^ 2-2} 

$
<span> The resctrictions of the function are those that make the denominator equal to zero.
We have then:
</span> $n ^ 2-2 = 0

n = +/- \sqrt{2} 
$
<span> Answer:
The simplified expression is:
</span> $\frac{n ^ 2-6}{n ^ 2-2}$
<span>The restrictions are:
</span> $n = \sqrt{2} 
$
$n = - \sqrt{2}$

If you have 9/10 of a pound of granola how many 1/5 pound bags can you fill ?

Lostsunrise [7]

Answer:

Step-by-step explanation:

1/5 is the same as 2/10. How many 2's can you put in 9? You can put 4.5 2's in a 9. However, filling half a bag does not fill the entire bag, so the answer would be 4. You can fill 4 full 1/5 pound bags with 9/10 pounds of granola.

jamal is making pancakes. He has 6 3/4 cups of batter, but he needs a total of 12 cups. How much more batter does Jamal need?

vampirchik [111]

Jamil has already 6 3/4 cups of butter.
He need 12. SO in order to get the needed butter, we subtract 6 3/4 to 12.

= 12 - 6 3/4
= 11 4/4 - 6 3/4
= 5 1/4

So Jamil needs 5 1/4 cups of butter to achieve the 12 cups.
