3495250

Step-by-step explanation:

~geometric sequence

common ratio: r=4

formula: Sn=a1(1-r^n)/1-r

Sn=10(1-(4)^10)/1-4

=-10485750/-3

=3495250

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
