I wanna make sure I got it right!!
Simplify the expression:
2(3n+4)-2(2n+5)

Answer 1

is it: 2n+18?

Answer 2

2(3n+4) = 6n + 8
-2(2n+5) = -4n+5

= 6n + 8 - 4n + 5

Answer 3

now if you simplify the last equation it would be:
2n-2

Answer 4

sorry wait it shoulde be -4n -10 for the 2nd equation above

Answer 5

simplifying 2n-2 further it would be 2(n-1)
