FOIL

3x*3x +3x*3 +3x*3 +3*3

9x^2 +9x+9x+9

9x^2 +18x+9

B=18

answer: i don't understand it

step-by-step explanation: sorry

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
