Answer:
If the shapes are congruent to each other by rigid transformations (probably).
You use pi in the equation to find the circumference and/or area of a circle.
Step-by-step explanation:
1. Both pairs of opposite sides are congruent <u>Distance Formula</u>
2. Both pairs of opposite sides are parallel <u>Slope Formula</u>
3.Diagonals are congruent <u>Distance Formula</u>
4. Diagonals bisect each other <u>Midpoint Formula</u>
5.Diagonals are perpendicular <u>Slope Formula</u>
6.Sides of polygon create a right angle <u>Slope Formula</u>
7.A triangle is isosceles / equilateral <u>Distance Formula</u>
Answer:

28.35
Step-by-step explanation:
Given
f(x) = 12x + 2
f^-1(x) = ?
Now
Let y = f(x)
or y = 12x + 2
Interchanging the role of x and y
x = 12y + 2
x - 2 = 12y
y = <u>x </u><u>-</u><u> </u><u>2</u>
12
Therefore f^-1(x) = <u>x </u><u>-</u><u> </u><u>2</u>
12
