Use the distributive property to rewrite the expression below in standard form 3(5a-2b+3c)

15a-6b+9c

Step-by-step explanation:

∴3 ( 5a - 2b + 3c)  = 15 a - 6 b + 9 c

Step-by-step explanation:

The distributive property of multiplication over addition is

m( a + b + c) = m a + m b + m c  where a , b, c are natural numbers and m is constant.

3( 5a - 2b + 3c) = 3 ×( 5 a) - 3 ×( 2 b) + 3 × (3 c)

       = 15 a - 6 b + 9 c

∴3 ( 5a - 2b + 3c)  = 15 a - 6 b + 9 c

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.

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
