<span>Consider the triangles ERT and CTR.
|ER|=|CT| shown
(</span>Therefore, one can say that segment ER is congruent to segment CT.)
m(R)=m(T)= 90°shown
(By the definition of a rectangle, all four angles measure 90°)
|RT|=|TR|
so we have Side Angle Side congruence.
By the <span>(SAS) Theorem, the triangles are congruent.
Answer: </span><span>C (SAS) Theorem</span>
A.) x(x-2)
x^2-2
B.) x(x+6)+3(x+6)
x^2+6x+3x+18
x^2+9x+18
C.) (x+3)(x+6)
x^2+6x+3x+18
x^2+9x+18
Answer:
.
Step-by-step explanation:
From Mathematics we remember that the domain of a functions corresponds to the set of values of the independent variable (
in this case) so that images exist and the range of a function is the set of images.
In this case, we know the domain and range of 
and we must find the domain and range of 
.
Domain
The domain of is the domain of . That is, .
Range
We have to define the bounds of the range of , given that range is modified by streching and horizontal translation operations:
Lower bound (
)
Upper bound (
)
In consequence, the range of is
