Answer 5

So would it be (4x+24) and (8x-13) or (12x-37)

Answer 6

You need to first add the length and width

2x + 12 + 4x - 13

2x + 4x = ?
12 - 13 = ?

And then you m ultiply the whole thing by 2. You'll have to distribute the 2. Remember the distributive property?
a(b - c) = ab - ac

Answer 7

Ok so 2x+4x is 6x and 12-13 is -1 so what after that?
