20a3-25a²b+8ab2-1063 (A) (5a²+2b)(4a-5b)
(C) (5a²+2b)(4a-5b)
(B) (5a-2b?)(4a+5b
(D)(20a²+2b2 )(a-5b​

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
