Answer: 11 < x < 35
suppose: the length of the third side is x
because x is the third side of a triangle
=> 23 - 12 < x < 23 + 12
⇔ 11 < x < 35
Step-by-step explanation:
Quadratic formula:
What do we have:

Cancel the common terms:
Answer:
one solution
5x - 30 = 3x + 60
2x - 30 = 60
2x = 90
x = 45
X= -19
