Answer:

20cm, 28cm, 40cm

Step-by-step explanation:

Let the shortest side be 4x, the middle side be 7x and the longest side be 10x.

4x + 7x + 10x = 105

21x = 105

x = 105 ÷ 21

x = 5

Shortest side (4x) = 5 × 4

Shortest side (4x) = 20

Middle side (7x) = 7 × 4

Middle side (7x) = 28

Longest side (10x) = 10 × 4

Longest side (10x) = 40

vampirchik [111]
The stock price per share was $8.60
Number of shares bought 1000
Total price for the shares:
(Cost per share)*(Number of shares)
=8.60*1000
=$8600

The stock price after 1 year $9.15
Total number of shares is 1000
Current price=(current share price)*(number of shares)
9.15*1000
=$9150
current value=(Current price)-(buying price)
=9150-8600
=$550

Net Profit=(Current value)-(Expenses)
=550-14
=$536
