Answer:
symmetric matrix is the square matrix and it is equal to its transpose
Step-by-step explanation:
solution
a symmetric matrix is the square matrix and it is equal to its transpose
As A is symmetric matrix then
A = 
here only square matrices will be symmetric
and matrix A is symmetric its mean its matrices have equal dimension
and every square diagonal matrix is also symmetric when all off diagonals element is zero
symmetric matrix for all indices i and j
A = aij = aji
Answer:
-3/5
Step-by-step explanation:
First, make the mixed fraction into an improper fraction:
-1 2/5 = -(5/5 + 2/5) = -(7/5)
Note that two negatives = one positive:
- (-4/5) = + 4/5
Combine the terms. Subtract the numerators:
-(7/5) + (4/5) = (-7 + 4)/5 = -3/5
-3/5 is your answer.

Answer:
The simplification is done below.
Step-by-step explanation:
= 
=
= 
If you convert the fractions to improper, you get 9/2 times 7/4. you can then just multiply the tops and bottoms and simplify! hope this helps
