Answer: 15=x
Step-by-step explanation:
a²+b²=c²
a=9
b=12
c=x=?
9²+12²=c²
81+144=c²
*square root* of 225= *square root* of c²
*square root* of 225= c
15=c
Step-by-step explanation:
To prove it we just use the definition of similar matrices and properties of determinants:
If are similar matrices, then there is an invertible matrix , such that (that's the definition of matrices being similar). And so we compute the determinant of such matrix to get:
(Determinant of a product of matrices is the product of their determinants, and the determinant of is just )
