You need to find the root of 69 since the length and width are multiplied to get the area, therefore it would be 8.3 inches.
The expression can be written as:
(2x + 5) - 3
or:
5 + (2x - 3)

and simplified to: "2x + 2" .

Step-by-step explanation:
Answer:
75.44 Square Inches
Step-by-step explanation:
The diagram of the problem is produced and attached.
To determine the area of the cleaned sector:
Let the radius of the larger sector be R
Let the radius of the smaller sector be r
Area of the larger sector 
Area of the smaller sector 
Area of shaded part =Area of the larger sector-Area of the smaller sector

From the diagram, R=10 Inch, r=10-7=3 Inch, 
Therefore, Area of the sector cleaned
