Answer:
A
Step-by-step explanation:
<h3>Numerator</h3>
(3x)(3x) = 9x^2
√9x^2 = 3x
Numerator = 3x
<h3>Denominator</h3>
√18y^2 = √18 · √y^2
√18 = 3√2
√y^2 = y
3√2y
Denominator = 3√2y
Now we need to rationalize the denominator, and get rid of the square root on the bottom
*
=
= 
The slope, if you have a graph, is the angle the line is going down so look at this graph:
Try 1(18) / 2
Just multiply 1 by 18 and divide 18 by 2.
Then we have 9!
Answer:
C'D'=10
Step-by-step explanation:
CB=5, and C'B'=12.5
5*2.5=12.5
4*2.5=10
