Which equation can be used to find 42 x 51?
(40 x 50) + (2 x 1) = 2,000 + 2
(4 x 5) + (2 1) = 20 + 2
(4 x 5) + (4 x 1) + (2 5) + (2 1) = 20 + 4 + 10 + 2
(40 x 50) + (40 x 1) + (2 x 50) + (2 x 1) = 2,000 + 40 + 100 + 2

(40 x 50) + (40 x 1) + (2 x 50) + (2 x 1) = 2,000 + 40 + 100 + 2

(40 x 50) + (40 x 1) + (2 x 50) + (2 x 1) = 2,000 + 40 + 100 + 2
