Answer:
19
Step-by-step explanation:
Given 2 sides of a triangle then the third side x is
difference of 2 sides < x < sum of 2 sides , that is
18 - 2 < x < 18 + 2
16 < x < 20
Then the largest possible length of the third side is 19
it it can be calculated by using the quadratic formula.
X=-b+_(√b^2-4ac)/2a
27
6f - 3g + 4h
6(2) - 3(-1) + 4(3)
12 + 3 + 12
