15 because simple division 30 divided by 2 is 15 only 15 can happen
If by next to you mean across from, it could be a parallelogram.
Perimeter of rectangle=66
length of rectangle=L
width of rectangle=w
P of a rect.= 2(length)+ 2(width)
66= 2L+2w
if the length is 7in more than the width, then
L=7+w
Now we will substitute 7+w in for L. Here is our new equation:
66=2(7+w) + 2w
Solve for w
66=14+2w+2w
66=14+4w
52=4w
w=13
L=7+13, so L=20
I hooe this is explained well enough
0 and 2 is the most logical answer
If u subtract 6-9 u would get a -3 because the 9 is bigger than the 6 so thats how you get a -3.
