Answer:
F(7) = 11
Step-by-step explanation:
F(7) = 2(7) -3
= 14 - 3
= 11
Consider the given parallelogram KLMN.
Prove: 
Statement Reason
1.
Definition of parallelogram
2.
Same Side interior angle theorem


3.
Substitution property

4.
Subtraction property of equality

Subtraction property of equality tells us that if we subtract some number from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same.
5.
Angle Congruence Postulate

When two angles are equal, then they are said to be congruent by Angle congruence postulate.
Answer:
91.14 feet
Step-by-step explanation:
Given:
In a park,a sidewalk is built around the edge of a circular pond.
The sidewalk is 7 feet wide, and the pond measure 15 feet across.
Question asked:
What amount of railing would be needed to go completely around the outer edge of the sidewalk?
Solution:
From distance from one edge of the pond to the another = 15 feet
That means diameter of the pond = 15 feet
And width of the sidewalk = 7 feet all around
combined diameter = 15 + 7 + 7 = 29 feet
Radius,r = 
That means distance between outer edge of the sidewalk to the center of the circular pond = 14.5 feet
Now, we will have to find circumference of outer circular edge of sidewalk:


Therefore, 91.14 feet would be needed to go around the outer edge of the sidewalk.
