Answer:
The solutions of the equation x² + 4x + 4 = 25 are:
First option: x= 3 or x= -7
Step-by-step explanation:
x² + 4x + 4 = 25
Equaling to zero: Subtracting 25 both sides of the equation:
x² + 4x + 4 -25= 25-25
Simplifying:
x² + 4x -21 =0
Factoring:
(x+7)(x-3)=0
Two solutions:
1.) x+7=0
Solving for x: Subtracting 7 both sides of the equation:
x+7-7=0-7→x=-7
2.) x-3=0
Solving for x: Adding 3 both sides of the equation:
x-3+3=0+3→x=3
The solutions are: x=3 or x=-7
Answer:
66 2/3 as a mixed number or 200/3 as an improper fraction.
Step-by-step explanation:
That would be 66 2/3.
0.6 recurring is 2/3.
A dilation. Dilations are not rigid motions, in other words, it changes the size of the shape. Transformations that keep congruence are reflections, translations, and rotations.
