You will want to check B, E, and F. Hope this helps!
Namely, if 800 is the 100%, what is 160 in percentage of it?

solve for "x"
We know that
a1=1
a2=3
a3=9
a2/a1=3/1----> 3
a3/a2=9/3----> 3
<span>common ration r is equal to 3
number of terms n is 12
The </span><span>Sum of geometric series is given by the formula
</span>Sum=a1*[1-r<span>^n]/[1-r]
</span>Sum=1*[1-3^12]/[1-3]-----> Sum=[1-3^12]/[1-3]----> [3^12-1]/[3-1]
<span>Sum=531440/2-----> 265720
the answer is
265720

Wellll, its going to come out as 3.2962962963. But you can always round it to 3.30.
Hope this helped
Answer:

Step-by-step explanation:
To add the polynomials
Remove parentheses:

Group like terms:

Add similar elements:

The Standard Form for writing down a polynomial is to put the terms with the highest degree first,its term of 2nd highest is 2nd etc..
In our case the standard form is
