6 0

Answer:  

2x + (-2x + 3) = 3

2x - 2x +3

0 + 3

3

2x-7 + (-2x) = -7

2x -2x - 7

0 -7

-7

-(5x -1) + 5x = 1

-5x +1 + 5x

-5x + 5x + 1

0 + 1

1

Step-by-step explanation: In addition, the parentheses help identify the individual addends. If adding a negative number, it is the same as subtracting. If there is a negative sign outside the parentheses, as in example c, you must distribute it: the signs of the numbers within the parentheses must be reversed when the parentheses are removed.

What is the area of the drumhead on the drum shown below? Round to the nearest tenth
Harman [31]
There is no image posted. However, I will tell you how to solve for the area of a drum head.

Drum head is a circle shape. We will use the formula of finding the area of a circle to solve for the area of a drum head.

Area of a circle = π r²

π is pi. It is equivalent to 3.14. Though there are still a lot of numbers after 4. To ensure uniformity, π is 3.14

r is radius. It is the line from the center of the circle to the edge of a circle.

if the diameter of a circle is given, simply divide the diameter by 2 to get the radius. 

Diameter is the line that starts from one end of the circle to the other passing through the midpoint of the circle.

Example:
The drum head has a diameter of 10. What is the area.

diameter is given, so we need to get the radius: 10 ÷ 2 = 5

Area = π r²
        = 3.14 * 5²
        = 3.14 * 25
Area = 78.50 square unit

Area is always in a square unit.
