Polly is climbing a rock wall. She starts by climbing up 12 feet. Then, she climbs down 3 feet to take a different route. From there, she climbs up another 8 feet. How far off the ground is she now

but which class are u may know that first

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 : )
