I am pretty sure it is 2, since you want either x to equal 0 so 4 for the first and 2 for the second and then you subtract to get 2
Answer:
Mount Everest rise
above sea level.
Step-by-step explanation:
Given:
Mountains are often measured by the distance they rise above sea level.
Mount Washington rises more than

Two sides are 34 and 14.
The third side can't be longer than (34 + 14) = 48, because the 34 and the 14
together could not reach from one end of it to the other.
The third side also can't be shorter than 20, because the 20 and the 14 together
could not reach from one end of the 34 to the other.
So 18 doesn't work. (18 + 14) = 32 ... they couldn't cover the 34 .
