Solve the exponential equation.

23x = 4x-1

Step-by-step explanation:

23x = 4x -1  

Subtract 4x form both sides

23x - 4x = 4x - 1 -4x

19x = -1

Divide both sides by 19

19x/19 = -1/19

x = -1/19

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
