Answer:
x=2,BA=DA which is7
Step-by-step explanation:
5x-3=3x+1
both sides share an angle and B=D right angles
5x-3x=1+3
2x=4
x=4÷2
x=2
BA=5x-3
BA=5(2)-3
BA=10-3
BA=7
DA=3x+1
DA=3(2)+1
DA=6+1
DA=7
Point B is located at (-6, 5)
Multiply each coordinate by the scale factor 3 to get
-6*3 = -18
5*3 = 15
The point B' is located at (-18, 15)
I did the math on calculator and got A.
Hope I could help (:
