Hi, I'm happy to help!
Parallel means that two lines are lined up in the same directions and will never intersect even if they were extended forever in directions.
Let's look at the first option of AB, and AD. We can see that both lines intersect at point A, so AB and AD are not parallel.
For the next option of CD and BE, we can see that both lines don't intersect and won't ever even if the lines were extended. So, CD and BE are parallel.
For the third option, we have BC and DE. These lines don't intersect and aren't in line to ever do so. Therefore, BC and DE and parallel.
The last option is AD and BC. These two lines will never meet, but, they aren't line up in the same directions. AD is traveling upwards while BC isn't. Think about being able to make a road out of the two lines, it would never work. AD and BC are not parallel.
<u>To sum it up: You should select the 2nd and 3rd options because those lines are parallel.</u>

I hope this was helpful, keep learning! :D
Answer:

d = 5
Given:
QSR is a right triangle.
QT = 10
TR = 4
To find:
The value of q.
Solution:
Hypotenuse of QSR = QT + TR
= 10 + 4
= 14
Geometric mean of similar right triangle formula:
Do cross multiplication.
Switch the sides.
Taking square root on both sides.
The value of q is 
.
Answer:
2-7i is the correct option.
Step-by-step explanation:
We have been given the complex number real part 2 and imaginary part 7 it can be expressed as:
2+7i
And the conjugate means in the complex number is opposite sign of imaginary part that is in general:
a+ib will have conjugate a-ib
So, the conjugate of 2+7i is 2-7i
Hence, Option d is correct.
