The perimeter p of the rectangle with length l and width w is:
p = 2l + 2w
that is, two times its length and two times its width, lets solve for the width w and substitute known data:
<span>p = 2l + 2w
</span>2w = p - 2l
w = (<span>p - 2l</span>)/2
w = (56 - (2*12))/2
w = (56 - 24)/2
w = 32/2
w = 16
therefore the width of the rectangle is 16 in
Answer:
6 miles
Step-by-step explanation:
first thing you need to do is find a number under 18 that can be multiplied by 3
3
6
9
12
15
18
and 18 is the 6th number and is 18, you can add the 2 extra fixed charge to that
they can travel 6 miles
but if you're talking about a fixed charge per mile then dont use this! ^^
(A)
(B)
But we assume 
is a function of 
alone, so there is not potential function here.
(C)
For (A) and (C), we have 
, which makes 
for both.
I would say true. Hope this helps :)
