The values are
and 
Explanation:
The expression is 
Simplifying, we get,

Since, both sides of the expression are equal, we can equate the corresponding values of A, B, C and D.
Thus, we get,
⇒
and 
Also, equating,
, we get,
and 
Thus, the values are
and 
Since the big triangle is an isosceles one, we conclude that the angles of the left triangle are: 32, 90 and 3x-10. Sinche the sum of this angles have to be 180° we have:

Solving for x, we have:

Therefore, x=22.67 and the answer is A.
Selections 2, 3, 5, 6 are polynomials.
1 and 4 are not. The coefficients don't have to be integers, but the powers of the variables need to be positive integers. In 1, you have x^-1. in 4, you have x^(1/2).
Answer:

Answer:
2/3
Step-by-step explanation:
The ratio of any corresponding coordinates will give the scale factor.
Using the x-coordinates of C' and C, we have ...
scale factor = C'/C = 4/6 = 2/3
The dilation scale factor is 2/3.
