Answer:
C
Step-by-step explanation:
To find the area of a composite figure, separate it into the regular parts which make the irregular shape. This shape is composed of a semi-circle and a rectangle. Find the area by finding the area of each shape.
Semi-circle:
The semi-circle has a diameter of 2 + 4 + 2 = 8. The area this figure uses the radius which is half the diameter. The radius is 4. To find the area substitute r = 4 into 
. However the semi-circle has a smaller circle cut out of it with radius 2. The area of the smaller circle is 
. The semi circle in the shape is the areas subtracted which equals 12π.
Rectangle:
The area of the rectangle is found using A = b*h = 2*5 = 10.
The total area is 12π + 10 meters squared.
Answer:
He applied the reflection to the pre-image first.
He used an incorrect angle of rotation around point P.

Answer:
x = 20
Step-by-step explanation:
Given
120 = 6x
Solve for x by dividing both sides by the multiplier 6
x = 
= 20
Answer:
The first set is a solution, the second is not.
Step-by-step explanation:
Testing by filling in the numbers into the equation:
(1, 1.5): x=1, y=1.5
⇒ 1.5 =? 
· 1 + 
⇒ 1.5 =? +
⇒ 1.5 =? 
⇒ 1.5 =? 1.5 ⇒ Correct: is indeed solution to the equation
(12, 4): x=12, y=4
⇒ 4 =? · 12 +
⇒ 4 =? 
+
⇒ 4 =? 
⇒ Incorrect: this is not a solution for the equation
