Answer
<u>sometimes</u>
* entries are the amount of numbers in the matrices*
{ 6, 0, 9, 7}
would have 4 entries
2*3 and 2*3 both have the same number of entries but are not defined
and 2*3 and 3*2 both have the same number of entries and are defined
so it can't be always or never.
Answer:
208
Step-by-step explanation:
{ed}-{3cb}+{4ba}-{2ea} = {(-15)*(-6)} - {3*5*(-2)} + {4*(-2)*4} - {2*(-15)*4}
={90} - {15*(-2)} + {16*(-2)} - {8*(-15)}
= {90} - {-30} + {-32} - {-120}
= 90 (--)30 (+-) 32 (--) 120
= 90 + 30 - 32 + 120
= 120 - 32 + 120
= 88 + 120
= 208
