<h2>
Answer:</h2>
The area of the remaining board in square feet is:
108 square feet.
<h2>
Step-by-step explanation:</h2>
The remaining area of board=
Area of the whole board-Area of square which is removed.
i.e.
Area of remaining board= Area of square of side length 12 feet-Area of square with side length 6 feet.
We know that the area of square with side length s units is given by: s² square units
Hence, we get:
Area of remaining board= (12)²-(6)²
i.e.
Area of remaining board= 144-36
i.e.
Area of remaining board= 108 square feet.
2, 7, 12
-18 + 5= -13
-13 + 5= -8
-8 + 5= (2)
2+ 5 = (7)
7+ 5= (12)
Answer:
The Linear equation is 
The Total Cost to rent canoe is $44.5.
Step-by-step explanation:
Given:
deposit to rent a canoe = $25.00
Hourly charge for visiting deep creek lake = $6.50 per hour
we need to rent the canoe from 12:30 to 3:30 PM.
We need to find the total cost to rent the canoe.
Now Total number of hours (h) 12:30 to 3:30 PM = 3 hours
Hence Total Cost will be equal to deposit to rent a canoe plus Hourly charge for visiting deep creek lake multiplied by number of hours to visit.
Hence framing in equation form we get;
Total Cost to rent canoe = 
hence the Linear equation is 
Solving the equation we get;
Total Cost = 
Hence the Total Cost to rent canoe is $44.5.
Problem 3
Circumference = pi*diameter
C = pi*d
C = 3.14*7.6
C = 23.864
C = 23.9
<h3>Answer: 23.9 cm</h3>
=======================================
Problem 4
A = area of square
A = side*side
A = 8*8
A = 64 square cm
B = area of circle
B = pi*r^2
B = 3.14*(5.5)^2 .... radius = 5.5 is half of diameter = 11
B = 94.985
C = area of shaded region
C = B - A
C = 94.985 - 64
C = 30.985
<h3>Answer: 30.985 square cm</h3>
=======================================
Problem 5
diameter = 6
radius = 3
area = pi*radius^2
A = pi*r^2
A = pi*3^2
A = 9*pi
A = 9*3.14
A = 28.26
<h3>Answer: 28.26 square millimeters</h3>
