Answer:
x = 9
y = 6
Step-by-step explanation:
ΔABC ~ ΔPQR
Therefore, corresponding sides of these similar triangles will be in the proportional.



x = 
x = 9
Similarly, 
y = 
y = 6
True: A face of a polyhedron is simply a flat boundary that helps forms the 3D solid.
Answer:x=−136
Step-by-step explanation: Step 1: Simplify both sides of the equation.
2+x=
