Answer:
7
-3
Step-by-step explanation:
You want to simplify: (3x³+2-x³) - (-5x³+2²+1)
(3x³+2-x³) - (-5x³+2²+1) = 3x³ + 5x³ +2 -x³ - 2²-1
=7x^3 - 3
Answer:
Correct answer is B. 0.08
Step-by-step explanation:
Answer:
the fractions need to be divided into 1
if not then add all the fractions up to make the bird house and its over 1 then the difference is one is the answer as she may need more than 1 day.
Step-by-step explanation:
The sum of first 8 terms of series is -130208
<em><u>Solution:</u></em>
Given that,
2 - 10 + 50 - 250 , ....
n = 8
Find the common ratio between a term and its previous term

Thus common ratio is same
This is a geometric series
<em><u>The sum of terms of geometric sequence is given as:</u></em>

Where,
r is the common ratio
n is the nth term
is the first term of series
From series,

Therefore,

Thus sum of first 8 terms of series is -130208
