Answer:
its 16
as we know the square root of 64 is 6 and when it is multiplied by 2 its answer is 16.
Step-by-step explanation:
You're using inverse operation to solve this equation. Now you just have to think about it. What number plus 20 would equal the same number squared? The answer would be 5, since
5+20=5^2
25=25
The statement above is true :)
Another number that would work for the equation would be x= -4
-4+20=-4^2
16=16
The statement above is also true so your answer would be x=-4 and 5
You're doing it exactly right! Keep on going! :)
