Question

Which expression represents the determinant of A=[-3 6]
[ 1 -6]
det(A) = (–3)(–6) – (1)(6)
det(A) = (–3)(–6) + (1)(6)
det(A) = (1)(6) – (–3)(–6)
det(A) = (–3)(–6) + (–1)(–6)

Answer 1

Answer:

a first experssion

Step-by-step explanation:

there is a mistake in question

we can only find det for a square marix but not the rectangular matrices

so det expansion is very easy

criss the elements fromtop 1x1 i.e -3 with the -6 subtract 6 x 1

then u will get the answer

please mark it as brainliest
