Answer:
Step-by-step explanation:
Given
varies directly with 
This means
∝
This can be written as:
where 
is the constant of proportionality.
We know that when 
then 
. Using this we can find value of .
so, we have
Dividing both sides by 8 to isolate .
∴ 
when 
then will be
∴ 
(Answer)
Answer:
71 and 72
Step-by-step explanation:
a+b=8
cd id divisible by 8.
ab=17,26,35,44,53,62,71
The only number above with a consecutive number of 8 is 71. (71 and 72)
8 months. Because 8 x 8 = 64.
Hoping this helps!!!:)
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).
