Answer: AB will be parallel to A'B'.
Step-by-step explanation: We know the definition of dilation about the centre. It is defined as the enlargement or shrinken of the original figure keeping the centre of dilation or the figure as fixed.
We are given ΔUVW and AB is perpendicular to UW. Now, if we dilate the triangle about the origin, then the triangle will either enlarge or shrink keeping the centre fixed.
Let us consider the enlarged triangle, ΔU'V'W' as shown in the attached figure. Also, line AB will move to the new position A'B'. We can clearly see that both the lines are parallel to each other.
Thus, the line segments AB and A'B' will be parallel too each other.

Step-by-step explanation:
11x-8
The volume of cylinder is 616 cm^3.
So if I understand this correctly, this would look something like this:
A first number
let's call it x
plus twice a second number
let's call the second number y:
x+2y=5
is 5.
this means that x=5-2y!
twice the first number plus the second totals 31.
2x+y=31
from the last one, i know that y=31-2x
and i can insert it into the first equation:
So i know that x=5-2y
and that
2x+y=31
i will substitute x here
2(5-2y)+y=31
remove the bracket
10-4y+y=31
10-3y=31
remove 10 from both sides
-3y=21
then
y=-7
and
x=5-2(-7)=5+14=19
