The answer is never, that is, on a 2 dimensional plane. You can perform an experiment to see why it is the case. On curved surfaces though, two lines can intersect one another more than once. For instance, on the surface of planet Earth, two lines can intersect one another, both at the Earth's North Pole and South Pole.
Answer:
C = 25.12 , A = 50.24
Step-by-step explanation:

C = 8 * 3.14 = 25.12
A = (4*4) * 3.14 = 50.24
O think it is c subtracting 6 because adding and subtracting is the same so it’s either c or d
Okay. So 3/5 in decimal form is 0.6. 7/10 in decimal form is 0.7. When you put them in order from least to greatest, the order would be 0.15, 3/5, 7/10, 0.85. Converting fractions to decimals and looking at the different places and what not could help make solving questions like these much easier.
Your Answer Is...
12.
