Use o fato de que o determinante de qualquer matriz quadrada é o mesmo da sua transposta.


Answer:
1,300
Step-by-step explanation:
First, we need to substitute all the variable with the given number.
To figure out the 2 equivalent squares, do 20 x 20 , which is 400.
Then, the 3rd triangle, do 28 x 25 , equaling 700.
Lastly, for the 2 triangles, 20 x 20 / 2 , leading to the solution of 200.
Now, putting everything together by adding 400+700+200, the final answer is 1,300.
I hope this helped!!

Answer:
2 000 miles
Step-by-step explanation:
In the first year, Mr James travels 8 x
miles = 8 000 miles.
The second year, he traveled 1 x
miles = 10 000 miles.
Comparing the distance covered in the two years,
10 000 miles - 8 000 miles = 2 000 miles
Therefore, Mr James travels 2 000 more miles in the second year than he did the first year.
Let's assume that Mr James conveys himself to his place of work all through the first year in his private car. But in the second year, there were some days in which the car was not available. So he had to go for his job by public transportation. This itch during those days, could cause an increase in the distance covered from his home to his place of work for the second year.
