So, let's take a look! When doing volume, we always do (addition) and nothing else. The only time that we would have to multiply is if we would have to find the area, but in this case, we are (going to figure) out what would be the volume.

We would sum up the following:

$\boxed{6+6+12+8*2}$ .

I believe that we would multiply this by (2) because we would have to find the other side as well.

And this would give us . . . 64 as it's volume.

V= (64)

<h3>Answer: Choice D</h3>

Explanation:

Any time Alyssa is increasing her speed, the graph will move uphill when going from left to right.

If she slows down, then the graph will move downhill when going left to right.

Always move from left to right when reading a graph because this is how the time axis is set up.

Any flat part represents portions where her speed is constant, i.e. doesn't change.

With all that in mind, the answer is choice D because

The first portion is going uphill (she's increasing her speed). This portion spans horizontally from 0 seconds to 20 seconds.
The next portion is her slowing down (the graph is going downhill). This portion spans horizontally from 20 seconds to 30 seconds (so we have a 10 second duration).
The third portion is where Alyssa is driving at some fixed speed that doesn't change. This portion is 20 seconds long.
The last portion is Alyssa slowing down and coming to a complete stop. This portion is 5 seconds long.

I need help I don’t understand

you'll first need to understand the symbols, I've attched a cheat sheet :)

you'll need to see if AB is linked to CD reversed.

If not then it's not A

For B you'll have to see if the angles are parralel to each other.

and for C you'll have to see if the angles are the same.

and D is the same as C

so the answer is ab=cd

<h2>now you understand :)</h2>
