Let a, b be an nx n invertible matrix, which of the following statements is/are always true? (i) (a + b)a b-1 (ii) (-i)t(a-1)3 (iii) det(aa) kdet(a) for any scalar k (iv) (ka)-1-k-1a-1 for any scalar k (v) a+ at is diagonalizable 0 a. (i) and (iii) only b. (ii) and (iv) onljy c. (iii), (iv) and (v) only v) and (v) only

take it another

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

answer: sensy

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
