sorry can't help didn't understand
Hello :
PA = PB or PA² = PB²
(5-b)²+(4-2)² = (2-b)² + (5-2)²
(5-b)²+4 = (2-b)² + 9
25 -10b +b² + 4 = 4 -4b+b² +9
-6b = -16
b = 8/3
Based on the calculations, the interest rate on the stock in four (4) years is equal to 7.1%.
<u>Given the following data:</u>
Amount borrowed (Principal) = $22,000.
Simple interest, I = $78.40.
Time = 4 year.
To determine the interest rate on the stock in four (4) years:
<h3>How to calculate simple interest?</h3>
Mathematically, simple interest can be calculated by using this formula:
I = PRT
<u>Where:</u>
- S.I is the simple interest.
- P is the principal or starting amount.
- T is the time measured in years.
Making R the subject of formula, we have:
R = I/PT
Substituting the given parameters into the formula, we have;
R = 6260/(22,000 × 4)
R = 6260/(88,000)
Interest rate = 0.071 = 7.1%.

Answer:
1. 8/35
2. 13/35
Explanation:
You add the numbers in the parentheses first, then you multiply
1. 1/5 + 3/5 = 4/5
4/5 * 2/7 = 8/35
———————————
2. 1/5 + 3/5 * 2/7
You would multiply 3/5 and 2/7 first
1/5 + 6/35
Then you find a common denominator
1/5 = 7/35
Then you add 7/35 and 6/35
7/35 + 6/35 = 13/35
