If the shapes are similar, the correspondent sides are in proportion:

Let's plug the values and solve for x:

Multiply both sides by x to get

The only feasible solution, though, is
, because it wouldn't make sense to have negative lengths.
Answer: M=1/3
Step-by-step explanation: We know how to find the slope by using the formula: y2-y1/x2-x1
Then we get 3-1/3--3=2/6=
1/3
The numbers are: 2, 3, 4, 5, 6, 7, 8, 9, 10, 11
Looks like the answer might be around 20 i think
I don’t think you can factor it any further
