What is the value of x? enter your answer, as a decimal, in the box. x=

x=3.5

The way to set these problems up is actually super easy, I usually stink at math but these are pretty easy for me. So here ya go...

How they teach it in class, you'd normally set it up like this: , (you might want to go ahead and set it up like that just to be safe, it's up to you), but in the end all your doing is cross-multiplying and dividing. So let me show you an easier way that I use:

Now I usually just multiply the whole numbers that are across from each other, so as you can see, 4.2 and 5 are across from each other (diagonally). When you multiply those together you get 21.

Now you divide 21 by 6. You do that because 6 is across from x, and by dividing you'll get x by itself. So x=3.5

Hope that isn't super confusing lol

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
