Answer:
15\lb of course
Step-by-step explanation:
all u do is subtract the rate of change an youll get your answer
3 over 1 + 6 over 60
[3 over 1 × 60 over 60] + 6 over 60
180 over 60 + 6 over 60 ➡ 186 over 60
186 over 60 ➡ 31 over 10
Then we divide 31 from 10 which give you the quotient of 3.1..
(((Meaning ➡ '"3.1" would be your answer)))

Therefore, a is 7 aka real part and b is 19 which is imaginary part.
