The identity (x^2+y^2)^2 = (x^2+y^2)^2 + (2xy)^2 can be used to generate pythagorean triples. what pythagorean triple could be generated using x=8 and y=3

4

Step-by-step explanation:

2x2-2

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

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
