Reflection over the y-axis:
(x, y) ⇒ (-x, y)
Reflection of that over the line y = x:
(-x, y) ⇒ (y, -x)
Rotation counterclockwise by 270°:
(x, y) ⇒ (y, -x) . . . . . . equivalent to reflection over y, then over y=x.
The appropriate choice is ...
C) Reflecting over the y-axis and then reflecting over the line y = x.

Answer:
x=29
Step-by-step explanation:
(x+3)+(x-1)+(x+1)=90
x+3+x-1+x+1=90
3x+3=90
3x=90-3
x=87/3
x=29
x+3=32
x+1=30
x-1=28
Checking
(x+3)+(x-1)+(x+1)=90
(29+3)+(29-1)+(29+1)=90
32+28+30=90
90=90
