Kevin will be left with 2 ounces of mixed nuts in the can

Step-by-step explanation:

Given

Total nuts = 16 ounces

As Kevin gave 1/2 of the nuts to his sister, he will be left with

$= \frac{1}{2} * 16\\= 8$

He is left with 8 ounces of mixed nuts

Simplify the rational expression. state any restrictions on the variable. n^4-10nsq+24/n^4-9nsq+18

astraxan [27]

Substitution: n² = t
1 ) t² - 10 t + 24 = t² - 6 t - 4 t + 24 =
= t ( t - 6 ) - 4 ( t - 6 ) = ( t - 6 ) ( t - 4 ) =
= ( n² - 6 ) ( n² - 4 )
2 ) t² - 9 t + 18 = t² - 6 t - 3 t + 18 =
= t ( t - 6 ) - 3 ( t - 6 ) = ( t - 6 ) ( t - 3 ) =
= ( n² - 6 ) ( n² - 3 )
The restrictions: n² ≠ 6, n² ≠ 3, n ≠ +/- √6, n≠ +/-√3
