The line VS is middle line of that trapezoid, so you know that it is
VS= (WR+UT)/2
so we will get that it is:
<span>40= (x^2+2 +2x^2+3)/2
x = 5
Therefore,
x^2 + 2
5^2 + 2
25 +2

Answer:
5022 estimate= 5020
18 estimate= 20
So, 5022/20
=251
Step-by-step explanation:
The questions says "about" so that means you have to estimate. First, you estimate the cans, then, you estimate the homerooms = 5022 and 20. Last, you have to divide, 5022/20
=251
