What is the least common multiple (lcm)of 2,3, and 6
laiz [17]
<h3>Answer:  6</h3>

Explanation:

List list the multiples of each value

  • multiples of 2 = {2, 4, 6, 8, 10, ...}
  • multiples of 3 = {3, 6, 9, 12, 15, ...}
  • multiples of 6 = {6, 12, 18, 24, ...}

In each list, we see 6 show up. This is the smallest multiple that is in common; therefore, the LCM is 6

Side note: The LCM is useful to help add and subtract fractions.

Geometry help. If x is the image of U under a dilation centered at P, what is the scale factor.
kupik [55]
A dilation pushes all points outwards, a factor of 2 would double the distance (in this case the point V)
every further step is then also an increase of the factor so
1->U (nothing changes)
2->V
3->W
4->X

so the correct answer is 4

Answer:

x=4√2cos(45°)

x=4

For the second diagram

tan(38°)=14/x
