I have the same questions as you i got a 100, so heres the one for the 7cm 2cm and 6cm 111.68
The zeros are (-4,0),(-3,0),(3,0)
They are both equilateral triangles. hope this helps if not let me know im sure i can find another reason
-23 - -39
equals -23+39 because 2 minus signs = a plus sign
-23+39=16
the answer is 16
