Help me please! Would be greatly appreciated! :)

MR=20

Step-by-step explanation:

These appear to be isosceles triangles, so their bases are equal on both sides. For the little triangle in the center, one side is 6, so the other will also be 6. Now the larger one has MN=4, so QR=4 as well.

6+6+4+4=20.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )
