Let z≥2. what is the remainder of 10^z −1 divided by 4?

The remainder is 3.

Step-by-step explanation:

We have to find out,

If z = 2,

∵ 99 ( mod 4 ) = 3,

Suppose,

Now,

Hence, our assumption is correct.

The remainder of divided by 4 is 3 where, z ≥ 2.

answer: i think it's a

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
