Answer:
Perimeter: 33.7 mm
Area: 54 mm
Step-by-step explanation:
If you do 12 + 9.7 + 12 you will get the perimeter, and to get the area you would use the formula A = 
x base x height. Since the base is 12 and the height is 9, you would do 12 x 9 x 0.5 to get 54 mm for the area of the triangle.
Answer:
r =
Step-by-step explanation:
The common ratio r is calculated as
r = 
= 
= 
=
H(x) = 1/4x would be the inverse
The inverse is h squared -1 (x) = 2/5x -8/5
-4/7 > -2
If it is greater it goes to the right, and if it is less it goes to the left.
-4/6 is located to the right of -2
