(x^2-5x+6)+(3x^2-8x-2)

4x^2-13x+4

Step-by-step explanation:

1. Add together all like terms ( so x^2+3x^2=4x^2)

2. once you add all your like terms. order the numbers from biggest to smallest (4x^2'-13x+4)

*You'll know which is biggest by the exponent!

Hope this helps

there will be 35 boys in each team. : )

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
