Which polynomial represents the sum below?
(3x^2 + 3) + (3x^2 + x + 4)

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

this is false ^.^ lol

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
