Don't answer if you don't know it if you say sorry i don't know it i will report you Determine whether 81a^2 − 25z^6 is a difference of two squares. If so, factor it. If not, explain why.
(9a + 5z^3)(9a − 5z^3)
(9a − 5z^3)(9a − 5z^3)
It is not a difference of squares because −25z^6 is not a perfect square.
(9a − 5z^6)(9a + 5z^6)

Step-by-step explanation:

good luck!

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
