Find the sum of (-4x^2-3x+2)+(2x^2-5x+1)

-2-8x+3

Step-by-step explanation:

First, since this is addition we can remove the parenthesis in the problem. This leaves us with -4-3x+2+2-5x+1.

From here, combine the like terms in the expression. -4 and 2 combine to -2, -3x and -5x combine to -8x, and 2 and 1 combine to 3.

Put all of your terms back together and you get -2-8x+3 as your sum.

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

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.
