Answer:
x = -4 and x = -14
Step-by-step explanation:
Our equation is (x + 9)² = 25
Applying the square root property we would need to take the square root of both sides:
This give us x + 9 = ±5
Here we have two equations since taking the square root gives us a positive and negative value
Our first equation is x + 9 = 5, and to isolate the variable we would need to subtract 9 from both sides, giving us x = -4
Our second equation is x + 9 = -5, and to isolate the variable we would need to subtract 9 from both sides, giving us x = -14
-2x+ 12 = x^2 +16
-2x -4 = x^2
-4= x^2 + 2x
-4= 3x
-4/3 = 3/3x
-1.333 (repeated) = x
Answer:
This statement is false. Exterior angles are the angles created when the sides of the triangle are extended.
Step-by-step explanation:
Exterior angles are the angle between the any reference side and line extended from the adjacent side.
the sum of exterior and interior angle is 180 as it lies on a straight line.
_______________________________________________
based on above definition the given statement becomes false.
Hence, correct choice is option third
