Seled the correct answer from each drop-down menu. ABC goes through a sequence of transformations to form A'B'C'. The sequence of transformations involved is a blank followed by a blank

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
