Which is the solution of x=2+√x-2? <br>x=2 <br>x=3 <br>x=2 or x=3 <br>no solution​
erik [133]
No Solution
x=2+ Square root of x-2
-2
x-2= Square root of x-2
2s cancel out.
x = Square root of x
Or you can just graph it and see no solutions

Some one help me on this one
aleksandrvk [35]
The answer is III only, or D. 


We can start to solve this by knowing what the HL theorem means. The HL theorem, like its name implies, shows says that if a hypotenuse and leg of a triangle are congruent to the hypotenuse and leg of a different triangle, then the triangles are congruent. The only triangle that we see a hypotenuse congruent in is in figure III. In figure II, those congruent sides are both legs while in figure I we just see 2 congruent angles. Now in figure III, we can also see that two legs are congruent because of the reflexive property. That means that the answer is III, or D.

Kendra used these steps to solve the equation 2x + 5 = 3 + 2(x + 1). Which choice describes the meaning of her result, 5 = 5?
alekssr [168]
The answer is A.
 If a redundant conclusion is reached in basic algebra this states that the variable holds all possible real values. 
If you algebraically solve Kendra's you do achieve the true statement 5 = 5 (leaving out D). And if you test any value of x for the equation it does hold true (getting rid of B). 
Hopefully this makes sense.
