Aboy is 10 years older than his brother. in 4 years he will be twice as old as his brother. find the present age and write an equation to solve for it.

x+10=2x-4

x+10+4= 2x-4+4

x-x+14=2x-x

14=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

a is the right answer
