Atriangle can be formed with side lengths 3 in, 5 in, and 9 in. true false

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 : )

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
