This is a hard one for me.
Sorry I can't help you!
@pooja195 Help her please.
Do you know what perimeter means?
isn't it like the base.
Which answer do you believe it is?
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.
So, what is `4 inches less than x` mean? (In like an equation)
okay. so what next
No, that means `x-4` 4 inches less than x means we have to do subtraction.
So two of this sides are \(\sf x-4\) and one side is x So that means since the perimeter equals to 19: \(\sf\Large (x-4) + (x-4) + x=19\)
So it would be 9?
@AbdullahM how do i post a different question?
You have to first close this question and open another one.
Thank you for helping me.
Also, show me your work for that last equation...
\(\sf\Large (x-4) + (x-4) + x=19\) we can make that: \(\sf\Large x-4 + x - 4 + x = 19\) Add like terms and then isolate x.
(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
