Find an invertible matrix P and a matrix C of the form(a -b b a) such that the matrix A = (2 -37 1 4) has the form A = PCP^-1. The eigenvalues of A are 3 + 6 and 3 - 6 with corresponding eigenvectors (6 + i i) and (6 - i i). A The matrices P and C are.
B. There is no matrix C of the form [a -b b a] and no invertible matrix P such that A = PCP^-1

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
