Answer:1/(3+x)=(1/3)
1
(1−(−x/3))
1/(3+x)=(1/3)1(1−(−x/3))
Use this fact that
1/(1−t)=
∑
∞
0
t
n
(∗)
1/(1−t)=∑0∞tn (∗)
where
|t|<1
|t|<1
. I mean take
t=−x/3
t=−x/3
and...
Note that
|−t|=|t|<1
|−t|=|t|<1
is the radius of convergence
Step-by-step explanation:
Answer:
a.
b. 
Step-by-step explanation:
You need to remember that:
1. The word "more" indicates Addition.
2. The "Difference" is the result of a Subtraction.
a. Then, knowing this information, you know that:
- "The difference of
and
" must be expressed as:

- Then, "Three more than the difference of
and
" is:

- "The difference of
and
" can be expressed in this form:

Therefore, "Three more than the difference of
and
is equal to the difference of
and
" is:
b. Solve for "s" in order to find its value:

Answer:
The answer is A.
You are dividing by 8, not 10.
Answer:
because there is an exact square number such as:4,9
.4 as a percentage is 40%
