What is 2A- 3B, if A =
12-13].and-[ -4 -2]

B.

Step-by-step explanation:

2A-3B

2 multiplied by 'A' and 3 multiplied by 'B'

You will get

2A- 12 6

2 10

3B- 9 3

-12 -6

you will then have to subtract the two matrices and you will get

- 3 3

14 16 which is the second answer.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
