10x − 39
5.5x − 9
5.5x + 9

Answer 3

yes @radar

Answer 4

O.K then sum up the three sides and see what you get?

Answer 5

its an expression not the sum

Answer 6

No, he's saying that the Perimeter is the sum of all sides.. so you have to add up all the sides:

P = (0.3x + 24) + (0.2x - 15) + (5x)

Simplify by combining like terms.

Answer 7

I know @greenlegodude57
