Dont answer if u dont know the answer pls

The answer is:

Step-by-step explanation:

(Presuming you wanted to add these)

From the image that is given/shown, this is matrices.

In matrices, the numbers will somewhat correlate with each other!

From what is stated, "Find 3M + 7N"

We must substitute in M and N for the pair of matrices that are given:

M =  and N =

You will then be left with:

3  + 7

when then need to add these together:

1) First Multiply the matrix by 3, you'll get:

(Each number in the matrix is being multiplied by the values: 3 or 7)

2) Then Multiply the matrix by 7, and you'll get:

3) Add the matrices:

6 - 35 = -29

-9 - 7 = -16

0 + 14 = 14

18 + 63 = 81

After solving the matrices, you get:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

i believe the answer is the polygon, heptagon.
