Answer:
1. x = +/- 2
- 7
2. x =
+/- 
3. n =
+/- 
Step-by-step explanation:
1. Divide both sides by 2: (x + 7)^2 = 8
Square root both sides: x + 7 = +/- 2
Subtract 7 from both sides: x = +/- 2
- 7
2. Square root both sides: x - 3 = 
Since there is a negative inside the radical, we need to have an imaginary number:
. So, 
Add 3 to both sides: x =
+/- 
3. Divide by -5 from both sides: (n - 2)^2 = -2
Square root both sides: n - 2 = 
Again, we have to use i: 
Add 2 to both sides: n =
+/- 
Hope this helps!
Answer:
43
Step-by-step explanation:
the line is worth 180 degrees. subtract 90 and 47 because that is part of the 180. your left with 43 degrees which is what is missing. hope this helps!
