Hello,
f(x)=2x^3+4x²-32x+18
f(3)=2*3^3+4*3²-32*3+18=12
Remainder =12
Vertical line is x=something
we see
(x,y)
(-2,3)
x=-2 is the equation
Answer:
32.59 (nearest hundredth)

<u>Geometric sequence</u>
General form of a geometric sequence: 
(where a is the first term and r is the common ratio)
Given:

Therefore:
<u>Sum of the first n terms of a geometric series</u>:

To find the sum of the first 20 terms, substitute the found values of a and r, together with n = 20, into the formula:
