1 answer:
The first dropdown box answer is "reflection over the y axis"
See the attached image.
Note how corresponding points simply have the x coordinate negated. For example, A and M correspond
A = (2,8)
M = (-2,8)
The only difference between these two points is the x coordinate is positive for A, and negative for M
The same applies for B and N, C and O, etc etc
Whenever you negate x coordinates only, a reflection over the y axis occurs. This is the rule (x,y) ---> (-x,y)
-----------------------------------------------------------------------------------
The second dropdown box answer is the second choice
We can see this by adding 3 to the x coordinate of point M to go from -2 to 1 (-2+3 = 1). So the answer must have point V with an x coordinate of 1. The only answer choice that fits is choice 2.

Answer:
50.2in or 4.2ft
Step-by-step explanation:
This is a problem about proportions so I generally set up my problems like below. I just set some variable here to make it easier to refer back to the measurements for each. You don't have to do this, I am just showing it for clarity. I will convert everything to inches too. We need to find the real window height.
Mb = model building = 18in
Mw= model window = in
Rb = real building = 678ft = 8136in
Rw = real window = ?
=
=
=
=
=
= Rw
= Rw
Rw ≈ 50.2in ≈ 4.2ft
