Answer:
B the service fee for coming to look at the machine
Step-by-step explanation:
Answer:
A = P(1+r÷100)^n
where A is amount after some days
r is the rate
n is the number of years
p is the principle (the amount of money before the interest)
A = 5000 ( 1 + 12÷100)^5
A = 8811.70
A = 8812
Answer:
Step-by-step explanation:
prime factorization
40y³ = 2³×5y³
625 = 5⁴
Greatest common factor = 5
40y³ - 625 = 5(8y³ - 125)
Note that 8y³ - 125 is the difference of cubes.
8y³ - 125 = (2y)³ - 5³ = (2y-5)((2y)² + 2y·5 + 5²) = (2y-5)(4y² + 10y + 25)
40y³ - 625 = 5(2y-5)(4y² + 10y + 25)
