Step-by-step explanation:
got it right on khan
The answer is 5b²/6c
Ok so you just have to simplify
15/18 = 5/6 (cause 3*5=15 and 3*6=18)
Then you do as the picture above says.
Perimeter: 2w+2l
We know the width and the perimeter, which is 18 and 76, so let's plug it in.
76=2(18)+2l
76=36+2l isolate the variable x!
40=2l
20=l
every length is 20 inches.
