Do you know what perimeter means?
anonymous
  • anonymous
Not really.
anonymous
  • anonymous
isn't it like the base.

  • misssunshinexxoxo
Which answer do you believe it is?
misssunshinexxoxo
  • misssunshinexxoxo
x+(x−4)+(x−4)=19
AbdullahM
  • AbdullahM
The perimeter means you add up all the three sides.

@misssunshinexxoxo To be honest i'm not sure. I don't know how to work it out.
AbdullahM

So, what is `4 inches less than x` mean? (In like an equation)
anonymous
  • anonymous
\[4
misssunshinexxoxo
  • misssunshinexxoxo
Yes
anonymous
  • anonymous
okay. so what next
AbdullahM
  • AbdullahM
No, that means `x-4` 4 inches less than x means we have to do subtraction.
anonymous
  • anonymous
oh
anonymous
  • anonymous
so 19-4?
AbdullahM
  • AbdullahM
So two of this sides are \(\sf x-4\) and one side is x So that means since the perimeter equals to 19: \(\sf\Large (x-4) + (x-4) + x=19\)
anonymous
  • anonymous
So it would be 9?
anonymous

@AbdullahM how do i post a different question?
AbdullahM
  • AbdullahM
You have to first close this question and open another one.
anonymous
  • anonymous
Okay.
anonymous
  • anonymous
Thank you for helping me.
AbdullahM
  • AbdullahM
Also, show me your work for that last equation...
anonymous
  • anonymous
okay
AbdullahM
  • AbdullahM
\(\sf\Large (x-4) + (x-4) + x=19\) we can make that: \(\sf\Large x-4 + x - 4 + x = 19\) Add like terms and then isolate x.
anonymous
  • anonymous
(x+x+x)+(−4+−4)=19 there are 3 x's. -4+-4=-8 3x+−8=19 3x−8=19 then I added 8 to both sides. 3x=27 then I divide both sides by 3 x=9

Great job! :D
