Find an ordered triple that represents 6y + 4z if y=(2,6,8) and z= (7,-2,6)

<40, 28, 72>

Step-by-step explanation:

y and z are the following vectors:

y = <2, 6, 8>

z = <7,  -2, 6>

To find 6y + 4z, first compute the scalar multiplications:

6y = <6*2, 6*6, 6*8> = <12, 36, 48>

4z = <4*7,  4*-2, 4*6> = <28,  -8, 24>

Then, add the obtained vectors, as follows:

6y + 4z = <12 + 28, 36 - 8, 48 + 24> =  <40, 28, 72>

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
