Droodle Review for Algebra II

 

You probably thought the title of this droodle was

"Two palm trees on a desert island" or maybe even

 

 

      "__    __ __ __ __ __ __    __ __ __ __    __ __ __    __ __    __ __ __ __ ."

       19    15  17  3 12 20 16    13 11 18  12    18 13 17    18 10    14 20 18 14

 

 

But the real title is

 

 

      "__ __    __ __ __ __ __    __ __ __ __    __ __ __    __ __ __ __ __ __    __

       19   9     20 19 16  6   8      1  11 16  7     13 12 17     5  19  2  15 12 18    19

 

 

                       __ __ __ __    __ __ __ __ __ __    __ __ __ __ ."

                       10 20 16  8     14 18 16 17  9  15    13 17 16  4

 

 

 

To determine the titles to this droodle, solve the 20 Algebra II SOL questions.  Then replace each numbered blank with the letter corresponding to the answer for that problem.
