Answer:
t(-6,2)
Step-by-step explanation:
t(-6,2)
t+2>-4
t+2<4
t>-6
t+2<4
t>-6
t<2
Using the given equation, take the square root of both sides. Both 169 and 9 are perfect squares, so the left side becomes plus or minus 13/3, which is rational. Six plus 13/3 is a rational number, and 6 minus 13/3 is also a rational number. If the solutions of a quadratic equation are rational, then the equation is factorable.

Step-by-step explanation:
• General quadratic equation:
• sum of roots → 4 + 5 = 9
• product of roots → 4 × 5 = 20
• substitute:

Answer: 33</h3>
=======================================================
Explanation:
The information that m || n is not needed or used, so I'm not sure why your teacher put that in there.
The angles shown are a linear pair. They are adjacent and they are supplementary. They form a straight angle.
Supplementary angles add to 180.
(x-17)+(5x-1) = 180
x-17+5x-1 = 180
(x+5x)+(-17-1) = 180
6x-18 = 180
6x = 180+18
6x = 198
x = 198/6
x = 33
---------
Extra info:
if x = 33, then,
- x-17 = 33-17 = 16
- 5x-1 = 5*33-1 = 165-1 = 164
Adding the angles gives 16+164 = 180 which helps confirm our answer.
