In the video, Rachel calculates 45 x 36 in the following way: 45 x 36 = (40+5)*(30 + 6) = (40 x 30)+(40 x6) + (5 x 30) + ( 56) = 1200 +240 + 150 + 30 = 1620 Using Rachel's strategy, what would the third line be for the problem 23 x 17? O A. (2x17) + (3 x 17) O B. (20 x 10) + (20 x 7) + (3 x 10) + (3x7) O C. (2x 10) + (2x7) + (3 x 10)+ (3x7) OD. (2 x 1) + (2x7) + (3 x 1) + (3x7)
