I don't know how to solve this. It's Algebra 2, Solving Exponential Equations

I hope you can read the attached photo of the process.

Step-by-step explanation:

This is a very strange equation. Whoever invented it wants you to apply some previous knowledge and come up a creative solution.

You know that 3 square is 9, the reciprocal of that is 1/9. Negative exponents result in reciprocals.

If you know that you can set up an equation using just the exponent given

You can make a quadratic equation  and solve that.

You get 2 possible values for x.

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
