explanation:

 | distribute the -5.5 into the parentheses

 | subtract 11 and move it over to -12.1

 | divide by -5.5

 | final answer

-5.5(d - 2) = -12.1

-5.5d + 11.0 = -12.1    distributed -5.5 on the left side

           -11.0    -11.0

-5.5d           = -23.1

               d = 4.2

d = 4.2

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
