I'm not sure how to solve this... Could anyone please help me?

the last one 2x-⁴y⁶

Step-by-step explanation:

-4 : - 2 = 2

x-³ : x = x-³-¹ = x-⁴

y⁴ : y-² = y⁴-(-²) = y⁴+² = y⁶

final

2x-⁴y⁶

215.92 dollars is the answer

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
