1. We're doubling to go from ABDC to A'B'D'C'. So AB=15 becomes A'B'=30 cm and BD=8 becomes B'C'=16 cm. Please see attached figure.
2. We have equal ratios
40:50:60 = 30:37.5:45
Let's check that. 30/40=3/4, 37.5/50=3/4, 45/20=3/4, all ratios the same, similar triangles.
We see the meets of the longest side and the shortest side are B and Z respectively.
The meets of the longest side and the medium side are C and X.
The meets of the short side and medium side are A and Y.
Pairing them up we have our

Answer:
2
Step-by-step explanation:
This implies
x+2=4
and
-(x+2)=-4.
x+2=4 implies x=2 since subtract 2 on both sides gives us x=2.
Solving -(x+2)=-4 should give us the same value.
Multiply both sides by -1:
x+2=4
It is the same equation as the other.
You will get x=2 either way.
Let's check:
Put both sides into your calculator and see if you get the same thing on both sides:
Left hand side gives 256/81.
Right hand side gives 256/81.
Both side are indeed the same for x=2.
