Answer:
x1=-1.06956, x2=1.66215
Step-by-step explanation:
X = 3 because you simplify 36/48 and it equals 3/4
Answer:
○ 
Explanation:
Accourding to one of the circle equations, 
the centre of the circle is represented by 
Moreover, all negative symbols give you the OPPOCITE TERMS OF WHAT THEY <em>REALLY</em> ARE, so you must pay cloce attention to which term gets which symbol. Another thing you need to know is that the radius will ALWAYS be squared, so no matter how your equation comes about, make sure that the radius is squared. Now, in case you did not know how to define the radius, you can choose between either method:
Pythagorean Theorem
Sinse we are dealing with <em>length</em>, we only desire the NON-NEGATIVE root.
Distanse Equation

Sinse we are dealing with <em>distanse</em>, we only desire the NON-NEGATIVE root.
I am joyous to assist you at any time.
No because if you were to square it you would get 5.099 and a perfect square is when it is the same number times each other to get a number for example: the square root of 9 is 3 so 3 times 3 is 9.
Hope that helps!
