3+√x+19-√2x replace x by 6===> 3+√6+19-√2*6 = 3+√6+19-√12
Note that √12 = √2x6 = √2 x √6 ===>3+√6+19-(√2) x (√6)
=√6(1+√2)+22
Answer:
Pre image of B' is B
Step-by-step explanation:
Given:
ABC is a triangle
A transformation is done on ABC so that the image is A'B'C'.
Note that transformations are of various types such as dilation, vertical shift, horizontal shift, rotation about a point, reflection on a line, etc.
In any type of transformation, corresponding vertices will be matched. In other words, A will become A', B will become B' and C will become C'.
Because of the property of the transformation to keep images similar and also transforming correspondingly the vertices we get preimage of B' would be nothing but B itself.

Answer:
x=3 one solution
Step-by-step explanation:
2x minus 6=-2x+6
2x+2x=6+6
4x=12
divide by 4
x=3
so it has one solution
