First you had to expanded form.
Finally you can also add by similar to elements.
Final answer: 
Hope this helps!

Answer:
True
Step-by-step explanation:
we know that
The <u><em>Trapezoid Mid-segment Theorem</em></u> states that : A line connecting the midpoints of the two legs of a trapezoid is parallel to the bases, and its length is equal to half the sum of lengths of the bases
see the attached figure to better understand the problem
EF is the mid-segment of trapezoid
EF is parallel to AB and is parallel to CD
EF=(AB+CD)/2
so
The mid-segment of a trapezoid is always parallel to each base
therefore
The statement is true
Answer:
-Conducting the survey on a holiday weekend will not produce representative results
-The survey was conducted using six similar flights
-The survey would not be a true representation of the entire population of air travelers
Step-by-step explanation:
First of all, the sampling method that was used in this survey/study was a convenience sampling, were they just used the data that was readily available, which in this case were the 6 flights from Boston to Salt Lake City.
This sampling method is useful for pilot studies and for identifying tendencies, however, the obtained sample is not representative of the population, and because there is no criteria to organize the sample, (for example there was no fight with a different route taking into account) it is impossible to obtain statistical results that are precise.
And besides that, the fact that the survey was carried out over Thanksgiving weekend is also a factor that can directly affect the results, so it needs to be taken into account as a variable, which in this study was not.

A=(−3,2,3)A=(−3,2,3)B=(−3,5,2) P=(2,−3,2) Q=(2,0,1) Is PQ−→−PQ→ equivalent to AB−→−AB→? A. no B. yes

Answer:
B. Yes, it is equivalent
Step-by-step explanation:
A = (-3, 2, 3)
B = (-3, 5, 2)
/AB/ = (-3-(-3), 2-5, 3-2)
= (0, -3, 1)
P = (2, -3, 2)
Q = (2, 0, 1)
/PQ/ = (2-2, -3-0, 2-1)
= (0, -3, 1)
So, /AB/ is equivalent to /PQ/
