The answer is the option B: A'(3, -2), B'(3, -5), C'(2, -4).
The explanation is shown below:
1. You must apply the following rule of rotation when the figure is rotated 90° counterclockwise around the origin:
→
2. Then, as you can see, you must switch 
and 
and multiply by -1.
3. Keeping this on mind, you have that the vertices of the triangle A'B'C' are the following:
A(-2,-3)→A'(3,-2)
B(-5,-3)→B'(3,-5)
C(-4,-2)→C(2,-4)
4. Therefore, you can conclude that the answer is the option B.
Step-by-step explanation:
Split the figure into 2 parts, triangle and rectangle (I believe you know what I'm talking about)
area of triangle = 1/2 x 20 x (16-7) = 90cm^2
area of rectangle = 20 x 7 = 140cm^2
total area = 90 + 140 = 230cm^2

Answer: Yes
Step-by-step explanation:
Since the numerator is multiplying square root 13 by square root 2, we can break them apart.
You are correct, 
over is equal to one, so we can "cancel them out" of our expression.
This leaves us with:
