Which of the equations are true identities? A. n3 + 3n² + 2n = n(n + 1)(n +2)
B. (a + 3)2 – 9 = a + 6a

Choose 1
Only A
Only B
Both A and B
Neither A nor B

2 x t divided by n

step-by-step explanation:

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

false
