For this case we have the following expression:
The difference of both numbers is:
We note that for number 14 we have:
tens place: 1
ones place: 4
Therefore, number 14 can be rewritten as:
Thus, the given expression can be rewritten by replacing values such as:
Then, for associative property we have:
We observe that the difference is also 8.
Answer:
the difference

Proof:
Let . As we chose
in
we know that
. Since
by transitivity we get:
.
If is the empty set, we already have that
. But if
is not empty, that means that it can't be subset of
, because
is already subset of
, and those sets do not share any element. In other words:
As can't be subset of
, then
.
was an arbitrary element, and
Thus, , where we conclude that
Answer:
Step-by-step explanation:
we are given
the sum,common difference and nth term of a geometric sequence
we want to figure out the first term
recall geometric sequence
we are given that
thus substitute:
to figure out we need to figure out the equation
simplify denominator:
simplify square:
simplify substraction:
simplify complex fraction:
calculate reciprocal:
reduce fraction:
multiply both sides by 4/7:
reduce fraction:
simplify multiplication:
hence,
