51 = 51
Answer:
(n-2)(n+2)
Step-by-step explanation:
The denominator of the second fraction is the difference of squares, so can be factored using the formula for that.
(n^2 -4) = (n -2)(n +2)
Now, you will note that the second fraction has a numerator that is equal to one of the factors in the denominator. In other words, the whole fraction can be simplified to ...
(n +2)/((n +2)(n -2)) = 1/(n -2) . . . . with the restriction n≠-2
This reduced form of the fraction has the same denominator as the first fraction, so you can say that the lowest common denominator is that: (n -2).
If there is some reason you don't want to reduce the second fraction, the lowest common denominator will be (n -2)(n +2).
Answer:
$515.35
Step-by-step explanation:
y-hat = 2.009x - 37.131
y-hat = 2.009(275) - 37.131
y-hat = 552.475 - 37.131
y-hat = 515.344
Therefore, the pizza parlor can expect a profit of $515.35 if it sells 275 pizzas.
