Answer:
Semicircle = 
semicircle = 
semicircle = 51.4
∴ the perimeter is 14 + 32 + 51.4
∴ The perimeter is 97.4 cm
Area 1 = 
Area 1 = 20 ÷ 2 = 10
Area 1 = 
Area 1 = 314.2
Area 2 = 14 × 32 = 448
Area = Area 1 + Area 2
Area = 762.2cm²

Answer:
(4, -6)
Step-by-step explanation:
A reflection across the y-axis means the point is equal but opposite distance from the y-axis. It begins at 4 units to the LEFT (negative) of the y-axis, so after the reflection, it should be 4 units the the RIGHT (positive) of the y-axis. This has no change on the y-value of the point, because no matter the y-value, the point will still be the same distance from the y-axis. Long story short, if you're reflecting across the y-axis, change the sign of the x-coordinate. If you're reflecting across the x- axis, change the sign of the y-coordinate. That's why the answer is (4, -6).
Step-by-step explanation:
-6 = 2/9 x
2/9x = -6
x = (-6)×9/2
= -27
Answer:
