Answer: C
n > 1 where n is an integer
(((x + y) / 3) + (1 / x)) / (5 + (15 / x))
The best way is to make it one fraction.
Multiply by ((3x/3x) / (3x/3x)) to remove the other fractions.
((x(x + y)) + 3(1)) / (5(3x) + 3(15))
(x^2 + xy + 3) / (15x + 45)
Then factor to simplify
(x^2 + xy + 3) / (3(x + 15))
Answer:
The measure of the side
is 8.8.
Step-by-step explanation:
Since
, then
,
,
and
. From figure we have the following relationship:
(1)
Where
is the proportionality ratio.
If we know that
, then the measure of side
is:
(1b)


(1c)


The measure of the side
is 8.8.
This is called a difference of squares which always factors according to the rule for factoring the difference of squares....
(a^2+b^2)=(a+b)(a-b) in this case:
9w^2-16 so
(3w-4)(3w+4)
