Which is a square matrix?
[ 2 3 -8 1 -5 19 0 -3 5.6 7.8 6 78]
[ 2 3 -8 0 -5 19 0 0 5 8 6 0]. [1 3 -9 8 2 2 0 5 16 1 -3 11] [3 1 9 8 2 2 0 5 16 1 3 11]

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

what do u need to know

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
