M = Undefined (because the line is perfectly vertical)
If there is only one solution, at x=-3, then the factor of (x+3) must be repeated. The equation must be equivalent to
... (x +3)² = 0
This multiplies out to give
... x² +6x +9 = 0
The value of m is 6.

For finding the square of a binomial, you can either use the special form you have memorized:
... (x +a)² + x² +2ax + a²
or you can use the distributive property.
... (x +a)² = x(x +a) +a(x +a)
... = x² +ax +ax +a² = x² +2ax +a²
Answer:
x is less than or equal to 16
Step-by-step explanation:
- 2 x x + 4 < 20
Isolate the variable
divide 2 from 2 = 0
x + 4 < 20
x is less than or equal to 16
