Answer:
440 square miles would be the answer :)
Step-by-step explanation:
Let’s take the width as ‘w’
Length = 10 + 3w
Perimeter = 2l + 2w
2 (10 + 3w) + 2w = 180
20 + 6w + 2w = 180
20 + 8w = 180
8w = 180-20
8w= 160
w= 20
Dimensions:
Width = 20 cm
Lengths = (10+3w) = 70 cm
2:1 since 50 is 2 times 25
Answer:
3, 6, 9, 12 is not geometric
Step-by-step explanation:
A geometric progression has a common ratio r between consecutive terms.
3, 6, 9 , 12
has a common difference of 3 between terms and is arithmetic
1, 5, 25, 125
r = 5 ÷ 1 = 25 ÷ 5 = 125 ÷ 25 = 5 ← geometric
4, 8, 16, 32
r = 8 ÷ 4 = 16 ÷ 8 = 32 ÷ 16 = 2 ← geometric
2, 6, 18, 54
r = 6 ÷ 2 = 18 ÷ 6 = 54 ÷ 18 = 3 ← geometric
The percent of change from 12 to 15 is 25%
