28. This equation satisfies the condition
-x - 10 = -17
29. You can use this equation
x/5 + 5 = 0
30. The error is dividing the equation first by 3. The solution should have been
3x + 2 = 15
3x = 15 - 2
3x = 12
3x/3 = 12/3
x = 4
31.
x/4 - 6 = 2
x/4 = 2 + 6
x/4 = 8
x = 8(4)
x = 32
the last pair is statements are true.
Answer:
The answer to the question
Step-by-step explanation:
The LKM angle is an enclosed angle. So its size is half the arc facing it.
LKM (angle) = ½ LM (arc)
The LMN angle is a shadow angle. So its size is half the size of the arc facing it.
LMN(angle) = ½ LM(arc)
so:
LKM = LMN
First, factor each expression by finding two terms whose product is equal to the c term and sum is equal to the b term.
x^2-x+6 --> (x-3)(x+2)
x^2-4 --> (x+2) (x-2)
Next, cancel the terms that are equal on the top and bottom.
You are left with the answer of: 
Hope this helps!!
