Answer:
10x-15y
Step-by-step explanation:
5(2x-3y)
10x-15y
Answer:
D: 109 cm
Step-by-step explanation:
The formula of circumference is

Diameter =

Hence, circumference =

rounded of to 109.
It’s 282 because if you add all those rhe divide you get the answer
A. False. Consider the identity matrix, which is diagonalizable (it's already diagonal) but all its eigenvalues are the same (1).
b. True. Suppose

is the matrix of the eigenvectors of

, and

is the diagonal matrix of the eigenvalues of

:


Then

In other words, the columns of

are

, which are identically

, and these are the columns of

.
c. False. A counterexample is the matrix

which is nonsingular, but it has only one eigenvalue.
d. False. Consider the matrix

with eigenvalue

and eigenvector

, where

. But the matrix can't be diagonalized.
