Answer:
5.5%
Step-by-step explanation:
To find the interest rate, use the equation: I = prt
I = Interest = $6,600
p = principal = $15,000
r = rate = unknown
t = time = 8 years
Now plug the numbers into the equation.
6,600 = 15,000 * r * 8
6,600 = 120,000 * r
Now isolate the variable by dividing both sides of the equation by 120,000.
0.055 = r
Now change the rate to a percent by moving the decimal point 2 digits to the right.
5.5% = r OR r = 5.5%

Answer:
13,780.8 feet
Step-by-step explanation:
1 mile = 1.609km
1 mile = 5,280ft
Convert 4.2km to miles
1.609km = 1 mile
4.2km = 4.2/1.609 miles
= 2.610 miles
Convert 2.610 miles to feet
1 mile = 5,280ft
2.610 miles = 2.610 × 5,280
= 13,780.8 feet
20x²-25x-105 factored is 5(x-3)(4x+7)
