This is quite difficult to try to explain so I'm going to set up some matrices to demonstrate as best as I can. If matrix A has 3 rows and 2 columns, it would be respresented as
. This matrix can only be multiplied by another matrix that has the same number off rows as the number of columns in A. For example, if matrix B has 2 rows and 3 columns, it would be represented as
. If we set them next to each other, it might be easier to see the rule:
. The 2's match, and the other numbers represent how your solution matrix will look. Your solution matrix will be a 3x3. Here is matrix A:
and here's B:
. We can multiply these according to the rules. The multiplication works like this:
. first row of A times first column of B: (1*1)+(2*4) = 9. that goes into row 1 column 1 of your solution matrix. Go va to row 1 in A but column 2 in B: (1*2)+(2*5) = 12. That goes into row 1 column 2 of your solution matrix. Next row 1 of A and column 3 of B: (1*3)+(2*6) = 15. That goes into the first row column 3 of the solutiong matrix. Now move to row 2 of A column 1 of B: (3*1)+(4*4) = 19. That goes into row 2 column 1 in your solution matrix. Next row 2 A, column 2 B: (3*2)+(4*5) = 26. That goes into row 2 column 2 solution matrix. Continue as I showed you. You should be fine.
Answer:
|x|=6 we have x1=-6 x2=6
|x|=3.2 we have x1=-3.2 x2=3.2
|x|=0 x=0
There are several information's already given in the question. Based on the given information's the answer can be easily deduced.
Base of the parallelogram = 3 1/2 feet
= 7/2 feet
Altitude of the parallelogram = 3/4 feet
Area of the parallelogram = base * Altitude
= (7/2) * (3/4)
= 21/8
= 2 5/8 square feet
I hope that this is the answer that has come to your required help.

Step-by-step explanation:
When you name two congruent triangles with the letters of the vertices, you keep the order of the corresponding vertices. That means, that when you say triangle GHI is congruent to JKL, the corresponding congruent angles are G = J, H = K, and I = L. regarding the sides, segment GH = segment JK, segment HI = segment KL, and segment IG = segment LJ. Then, the answer is that, of the four options,<span> the one that is not true is the option c, because as we already said the corresponding equal segment to GH is JK and not KL.</span>
