Answer:
<h2>8/4</h2>
We have,
3+4(w+5)
=31 Or, 3+20+4w
=31 or, 4w
=31−23
w=8/4
Thus, w comes out to be 2 .
Step-by-step explanation:

Answer
Part A
None of the expressions given is the answer. The answer is w=V/(l*h)
PART B
w=8cm
Step-by-step explanation:
Part A
From the formula given to calculate the volume, we have to isolate the with w:
![V=l*h*w\\V/(l*h)=w](https://tex.z-dn.net/?f=V%3Dl%2Ah%2Aw%5C%5CV%2F%28l%2Ah%29%3Dw)
PART B
We know the formula to calculate with from Part A. Next, we replace given values in the formula.
w=V/(l*h)
w=120/(5*3)
w=120/15
w=8 cm
