Simplify (3x+1)^2-4(2x^2-3)

+6x+13

Step-by-step explanation:

Distribute:

=9x2+6x+1+(−4)(2x2)+(−4)(−3)

=9x^2+6x+1+−8x^2+12

Combine Like Terms:

=9x^2+6x+1+−8x^2+12

=(9x^2+−8x^2)+(6x)+(1+12)

=x^2+6x+13

answer: 10 meter

step-by-step explanation:

need details

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
