Given: 12 – x² = 0 ;
Multiply BOTH side by "-1" ;
__________________________________________________
-1 (12 – x² = 0) ;
to get:
-12 + x² = 0 ;
Rewrite as:
x² - 12 = 0 ;
Add "12" to both sides; to get:
x² = 12
Take the square root of each side:
√(x²) = ±√(12)
x = ± √(12)
_________________________________________________
√(12) = √(4) * √(3) = 2 √(3)
√(12) = 3.4641016151377546 ; round to: 3.464 .

The given equation is
And the graph of f(x) is translated 7 units to the left . So in case of left translation , we have to add 7 within the function , that is
As we see that 7 is added within the function not with the function f(x) . And that's the required function of g(x) .
30 + .15x = 20 + .20x
10 = .05x
200= x

Answer:
Maybe
Step-by-step explanation:
If we only have the same angle measurements, the triangles are similar.
We do not know if they are congruent unless we have at least one side measurement. They may or may not be congruent.
We cannot say if they are congruent
