Answer with the right formula everyone keeps getting it wrong.

The perimeter is the length of the edges added up, The sides of this triangle are 7x, 19x and 14, so for the first answer you get 7x + 19x + 14. To simplify, you combine the like terms, which would be 7x + 19x which equals 26x, so your final answer is 26x + 14. I hope this helps!

The interest rate needs to be 9.8% for the sum of $4000 to compound to $240,000

Step-by-step explanation:

Since the interest compounds itself, hence the question concerns the compound interest.

Details provided-

Principal (Initial contribution)- $ 4000

Amount (Expected amount)- $ 240,000

Time period- investment started at 22 years and would continue until 66 years.

Time period= 66-22 years= 44 years

Rate of interest=

We know that for compound interest-

⇒Amount= principal (1+rate/100)ⁿ

Substituting the values if Amount, principal and time ("n") in the above equation

240,000= 4000 (1+rate/100) ⁴⁴

240,000/4000= (1+rate/100) ⁴⁴

Solving the above equation would yield us with the rate as 9.75% ≈ 9.8% (rounded off to tenth place after decimal)

Hence the Interest rate required by John would be 9.8%
