Which of the following is the surface area of the right cylinder below? 9
A. 1621 units2
O B. 1747 units2
C. 1877 units2
O D. 1987 units2

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

215.92 dollars is the answer
