Answer:
1.) A diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle.
2.) 8
3.) 201 square inches
Step-by-step explanation:
The difference (subtraction) of 6 times a number (x represents number) and 7. This gives us 6x-7. That is equal to five times (multiplication) the sum (addition) of the number, x, and 4. This gives you = 5(x+4) and combined gives us B, 6x-7=5(x+4).
Answer: Divide 2 by 6- 0.3 with a bar over the 3, Step-by-step explanation: 0.3 with a bar over the 3 is the decimal form of 2/6
4y-6y+10
10y+10

Guessing and checking isn't the best solution, so I will demonstrate it another way.
Let x be the width. We know that the length is then 2x+5.
So, 2(x+2x+5)=100
3x+5=50
3x=45
So, x=15.
Therefore, the rectangle is 15 centimeters wide.
Guessing and checking could also work. Once you plug in a value, if it is less than 100, than increase you number. The other way works as well.
