For question 13, I got -15 and 8 as my answer and so did my other friends, but when they wrote the answer in the description most of them switched it to positive 15 for some reason, but I don’t understand how would it change to a positive. Idk if whatever I said really makes sense or not, but if any of you could help the would be really helpful

Bro , there's something in math called LOGIC
in questions like these that talk about something in real life, length , width , height,
ITS IMPOSSIBLE TO BE NEGATIVE

so don't care about -15 , yeah its a solution, but have u asked ur self solution for what ?

8 , -15 , r solution for equations

But what's logic to be a length is 8 cm

So the right side of rectangle (w) equals 8 cm

And the other is w+7 , whats the value of w? It's 8
So it becomes , 8+7 = 15 cm

That's how ur friends answered 15 cm (positive)

Got it?
