Step-by-step explanation: 6 faces, 12 edges, 8 vertices
Answer:
2:5
Step-by-step explanation:
Because if we look 8:20 can be turned into 8/20 and if we simply we got 2/5 and turn it into 2:5
Answer:
y = -4
Step-by-step explanation:
-2x + 5y = 8
Let x=-14
-2(-14) +5y = 8
28 +5y = 8
Subtract 28 from each side
28-28 +5y = 8-28
5y = -20
Divide by 5
5y/5 = -20/5
y = -4
