Answer:
12 + 8k² + k³ - 9k⁴
Step-by-step explanation:
(8 + k³ - 6k⁴) + (4 - 3k⁴ + 8k²)
8 + k³ - 6k⁴ + 4 - 3k⁴ + 8k²
(8 + 4) + (8k²) + (k³) + (-6k⁴ -3k⁴)
(12) + (8k²) + (k³) + (-9k⁴)
12 + 8k² + k³ - 9k⁴
Answer:
ans 3
Step-by-step explanation:
Circumference is distance round a figure. When diameter is trippled, the circumference will also tripple.
Here is a proof
Take the moon to have circular shape and has diameter d
Circumference is given by C=πd
When the new diameter is trippled, diameter will be 3d and the new circumference will be
C=π3d=3πd
Evidently, the new circumference is three times the original circumference. Therefore, for this case, the new circumference will be 3 times the original
