Answer:
2d NOT a proportionate relationship
Step-by-step explanation:
s = Δy/Δx
s1 = (6 - 12) / (-3 -(-6)) = -6/3 = -2
s2 = (-6 - 6) / (3 -(-3)) = -12/6 = -2
s3 = (-10 - (-6)) / (6 - 3) = -4/3 = -4/3
Answer:
The surface area of the lower rectangle is 20cm x 4cm= 80 square cm
the surface area of the two triangles is 12 square centimetres
the surface area of one of the top rectangular faces is 20×5= 100 square centimetres
the surface area of the other is 20×3= 60 square centimetres
80+12+60+100=252 square centimetres is the surface area of the polyhydron
3 4/9 would be the correct answer
