Assuming the sequence goes on like this 11,-33,99,-297,891,...,
its general formula is
So, the 9th term is
6.14, and 9.21 are two decimals equivalent.
There’s A. (9•9)^x
B. 9•9^2x
C. 9^x•9^x
D. 9^2•9^x
E. 9•9^x
F. 9^2x
That means:
1) you cannot factorize it, or
2) the binomial is not the right one to be the quotient or
3) the roots of the binomial are not the roots of the polynomial
To find the area of a polygon you have to write the formula of it which is area= 1/2 x perimeter x apothem . hope this helps
