Answer:
x = −4 and x = 4
Step-by-step explanation:
4x² = 64
Lets get x² on its own. To do this we divide each sides by 4:
x² = 16
Now to get just x, we need to square root this answer:
√x² = √16
x = √16
x = 4
But this can be ±4 as it -4 and 4 squared both give 16.
So your answer is x = −4 and x = 4

Answer:
Daniel =Were you thinking of perpendicular lines?
Oris= It seems like you've got the basic idea, but your definition could be more precise.
Kaoris= Yes well done...
4 ( x + 5 ) = x + 8
4 * x + 4 * 5 = x + 8
4 x + 20 = x + 8
4 x - x = 8 - 20
3 x = -12
x = -12 / 3
x = - 4
hope this helps!
