Considere uma matriz A quadrada de ordem n. Sejam também as seguintes matrizes: B1, que se obtém de A somando à linha i desta matriz uma constante k; B2, que se obtém de A subtraindo à linha i desta matriz a mesma constante k. Mostre que: | A | = 1/2 ( | B 1 | + | B 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.

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
