Answer:
Step-by-step explanation:
Given
Smaller
Bigger
Required
The ratio of the perimeter of smaller to larger
The ratio of the perimeter is the same as the ratio of the side lengths.
Considering the largest, sides:
We have:
Divide by 3
The equation is
2p=p (1+r)^t
2=(1+r)^t ....equation
Where r is the interest rate 0.05
Solve the equation for t
T=log (2)÷log (1+r)
T=log(2)÷log(1+0.05)
T=14.2 years
round your answer to get
T=14 years

Answer:
x = 11
Step-by-step explanation:
2x + 16 = 5x - 17
+ 17 + 17
2x + 33 = 5x
- 2x - 2x
33 + 3x
33/3 = 11
3x/3 = x
