For the set a = {0, {1}}, determine a2 = a * a

Assuming that you refer to as the Cartesian product of A with A, then remember that the cartesian product of two sets A and B is the set

Then, if ,

22 dimes and 9 nickels

step-by-step explanation:

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
