180a^3+900a^3+4a-5
__________________ + a-1/ 6a^a
6a ( a+ 5)
Answer:
Step-by-step explanation:
discriminant = (-13)² - 4·2·15 = 49
discriminant > 0 so there are two real roots
95 because if you do the math you’ll get the answer
after 1 year he will get : 800 + 800 x 3,5% = 800 x 1,035 = $828
after 2 years he will get : 828 x 1,035 = 800 x 1,035 x 1,035 = 800 x 1,035²
so
after n years he will get : 800 x 1,035ⁿ
