( A u B) would be the combination of both sets.
Since both sets have all distinct numbers, just add the 2 sets together.
4 + 7 = 11
There are 11 elements.
Answer:
4
Step-by-step explanation:
when all the lengths are multiplied by x (length scale factor), the volumes are multiplied by x³ (volume scale factor).
∴ when volume scale factor = 8
the length scale factor = ∛8 = 2
while When all the lengths are multiplied by x (length scale factor), the areas are multiplied by x² (surface area scale factor).
∴ when the length scale factor = 2
the surface area scale factor = 2² = 4
The ratio is 14:5, as 42 divided by 3 is 14 and 15 divided by 3 is 5.
