is the same thing as 1/a². So,
is 1/25. This is multiplied by 3² which is 9, so this is 9/25.
In the denominator, we have
, which is 1/5. We multiply this by 3, which is 3/5.
So, we divide 9/25 by 3/5, giving us 3/5.
Now, we raise this to the power of -2, so we flip the numerator and denominator and then square both numbers, giving us 25/9.
Have a wonderful day! :D
Answer:
C
Step-by-step explanation:
For two shapes to be similar they must have a set ratio. The only one that does have a set ratio is Y.
So the answer is C
The ratio is 1 : 2
1 * 2 = 2 = w = Yw (the width for rect y)
2 * 2 = 4 = l = Yl (the length for rect Y)
