You need an even number of reflections to get the original figure, leaving only A and D as potentially viable choices.
The reflection across the x-axis makes the tranformation (x, y) ⇒ (x, -y).
The reflection across the line y=x makse the transformation (x, y) ⇒ (y, x).
The two pairs of transformations of A give
(x, y) ⇒ (x, -y) ⇒ (-y, x) ⇒ (-y, -x) ⇒ (-x, -y) . . . . . not the original
The reflection across the y-axis makes the transformation (x, y) ⇒ (-x, y).
The two pairs of transformations of D give
(x, y) ⇒ (y, x) ⇒ (y, -x) ⇒ (-x, y) ⇒ (x, y) . . . . . . the original point
Selection D is appropriate.
99 x 0.17 = 16.83 feet every minute
16.83 x 3 = 50.49 meters below the ground

Answer:
Step-by-step explanation:
Using perimeter =2(l+b)
74=2(L+B)
From the question
Width(b)=x & length(l)=3x+5
So we have that
74 =2(3x+5+x)
Adding like terms we then have that
74 =2(4x+5)
Opening the bracket gives
74=8x +10
Collecting like terms
8x=74-10
8x= 64
Therefore
X=64/8
X=8feets
The width is 8feets
