Omar says that the least common multiple of 9 and 6 is 54. which is true about omar's statement?

It is not true. You can "see" quite easily that 9x2 = 3x6 = 18.

Here's the trick to find the least common multiple:

Factorize both numbers:

9 = 3 x 3

6 = 3 x 2

Now for each factor, take the case of the most occurrances.

For 3 it is two times in 9, so we take 3x3

For 2 it is once in 5, so we take 2

Multiply these:

3x3x2 = 18, the least common multiple.

Another example: LCM(30, 45)

30 = 2 × 3 × 5

45 = 3 × 3 × 5

2 x 3x3 x 5 = 90

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
