Find the characteristic polynomial of the matrix, using either a cofactor expansion or the special formula for 3 times 3 determinants. [note: finding the characteristic polynomial of a 3 times 3 matrix is not easy to do with just row operations, because the variable lambda is involved.]

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

yes the data was not prsented

step-by-step explanation:

for certain loans like mortgage loans, lenders scrutinize your debt to income ratio when you are applying for credit because it them evaluate your ability to repay your debts.
