Answer:
10x - 20
Step-by-step explanation:
First, factor both polynomials.
2x - 4 = 2(x - 2)
5x - 10 = 5(x - 2)
The LCM is the product of the common and not common factors with larger exponent.
LCM = 2 * 5 * (x - 2)
LCM = 10(x - 2) = 10x - 20
4 of 9
so 4/9 = 0.44444444444444444444444444444repeating
(sorry, not sure how to get bar notation for that)
