Step-by-step explanation:

Hessenberg matrix- it a special type of square matrix,there there are two subtypes of hessenberg matrix that is upper Hessenberg matrix and lower Hessenberg matrix.

upper Hessenberg matrix:- in this type of matrix  zero entries below the first subdiagonal or in another words square matrix of n\times n is said to be in upper Hessenberg form  if ai,j=0

for all i,j with i>j+1.and upper Hessenberg matrix is called unreduced if all subdiagonal entries are nonzero

lower Hessenberg matrix:-  in this type of matrix  zero entries upper the first subdiagonal,square matrix of n\times n is said to be in lower Hessenberg form  if ai,j=0  for all i,j with j>i+1.and lower Hessenberg matrix is called unreduced if all subdiagonal entries are nonzero.

Given:
3 teaspoons of salt for every 5 cups of flour.

How much salt is needed for 15 cups of flour?

This is a proportion problem:
a/b = c/d where ad = bc

3/5 = x/15
3*15 = 5x
45 = 5x
45/5 = x
9 = x

C. 9 teaspoons of salt is needed for 15 cups of flour.

3/5 = 9/15
3*15 = 5*9
45 = 45
