An LCM is the least common multiple, so it must be larger than 36 and 27. 63 is obviously not a multiple of 36 and 27. What about 108?
(2)
2(2x+3) = 4X + 6 - No
2(4x+3) = 8X + 6 - Yes -- it's the same as the model
8(x+6) = 8x + 48 - No
x(8+6) = 8x + 6x - No
(1). What is the least LCM of 36 and 27?
9
63
108
972
(2). Write an equivalent expression for 8x + 6 using the distributive property.
2(2x+3)
2(4x+3)
8(x+6)
x(8+6)
