Find the following determinant without using a calculator. show your work. 1 3 3 4 0 1 2 -5 | 2 5 4 3 |-3 -7 -5 2

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.

step-by-step explanation:

isn't it a pentagon? sense [3 (triangle) + 4 (rectangle)] - 2 (triangle and rectangle connected) = 5 (pentagon)

you would 18 *0.25 = 4.5
