The top one is 20 times as much but I really don't understand how to explain it.
Answer:
25%
Step-by-step explanation:
From the question given above, the following data were obtained:
Total shaded checker board (T) = 32
Shaded checker board with pieces (S) = 8
Percentage of Shaded checker board with pieces =?
We can obtain the percentage of checker board with pieces as follow:
Percentage of Shaded checker board with pieces = Shaded checker board with pieces / Total shaded checker board × 100
= S / T × 100
= 8 / 32 × 100
= 25%
Therefore, percentage of Shaded checker board with pieces is 25%
That would be D. Adjacent because they share a side.
Answer is a because a^-2 will be changed to 1/a^2
Hope that helps
