Area of rectangle is 7x9 which is 63
Area of the square=5x5 which is 25
So area is: 63-25=38
The answer would be the sequence has a common ratio of 4.
The explanation for this would be:
To get the common ratio for get the simplest form of the two numbers, so 12/3 = 4 and 48/12 = 4So we know that their common ratio is 4.
To check:
3 x 4 = 12
12 x 4 = 48
48 x 4 = 192
192 x 4 = 768
The answer is 80.5 ... 805 / 5
Create a proportion:
1 in/15 mi= x in/25 mi
15x=25
